In the Old Testament, the word Moab designates (1) a son of Lot by his elder daughter (Gen., xix, 37); (2) the people of whom this son of Lot is represented as the ancestor (Ex., xv, 15, etc.), and who are also called "the Moabites" (Gen., xix, 37); and possibly (3) the territory occupied by the Moabites (Num., xxi, 11). Its etymology: "from my father", which is added by the Septuagint to the Hebrew text in Gen., xix, 37, is more probable than any derivation suggested by modern scholars. (Bible Encyclopedia)
* While the Moabites adored Chamos as their national god, they also worshipped Ashtar as his consort. Besides these two divinities, the Old Testament mentions another local deity of the Mobaites, viz. Baal of Mount Phegor (Peor: Beelphegor) (Num., xxv, 3; Deut., iv, 3 Osee, ix, 10; etc.). The Moabites were therefore polythiests. And although their religion is not fully known, it is certain that human sacrifices and also impure rites formed a part of their worship (IV Kings, iii, 27; Num., xxv; Osee, ix, 10).

1. Elimelech’s care to provide for his family, and his taking his wife and children with him, were without doubt commendable. If any provide not for his own, he hath denied the faith, 1 Tim. 5:8. When he was in his straits he did not forsake his house, go seek his fortune himself, and leave his wife and children to shift for their own maintenance; but, as became a tender husband and a loving father, where he went he took them with him, not as the ostrich, Job 39:16.
But, 2. I see not how his removal into the country of Moab, upon this occasion, could be justified. Abraham and Isaac were only sojourners in Canaan, and it was agreeable to their condition to remove; but the seed of Israel were now fixed, and ought not to remove into the territories of the heathen. What reason had Elimelech to go more than any of his neighbours? If by any ill husbandry he had wasted his patrimony, and sold his land or mortgaged it (as it should seem, ch. 4:3, 4), which brought him into a more necessitous condition than others, the law of God would have obliged his neighbours to relieve him (Lev. 25:35); but that was not his case, for he went out full, v. 21. By those who tarried at home it appears that the famine was not so extreme but that there was sufficient to keep life and soul together; and his charge was but small, only two sons. But if he could not be content with the short allowance that his neighbours took up with, and in the day of famine could not be satisfied unless he kept as plentiful a table as he had done formerly, if he could not live in hope that there would come years of plenty again in due time, or could not with patience wait for those years, it was his fault, and he did by it dishonour God and the good land he had given them, weaken the hands of his brethren, with whom he should have been willing to take his lot, and set an ill example to others. If all should do as he did Canaan would be dispeopled. Note, It is an evidence of a discontented, distrustful, unstable spirit, to be weary of the place in which God hath set us, and to be for leaving it immediately whenever we meet with any uneasiness or inconvenience in it. It is folly to think of escaping that cross which, being laid in our way, we ought to take up. It is our wisdom to make the best of that which is, for it is seldom that changing our place is mending it. Or, if he would remove, why to the country of Moab? If he had made enquiry, it is probable he would have found plenty in some of the tribes of Israel, those, for instance, on the other side Jordan, that bordered on the land of Moab; if he had had that zeal for God and his worship, and that affection for his brethren which became an Israelite, he would not have persuaded himself so easily to go and sojourn among Moabites.
IV. The marriage of his two sons to two of the daughters of Moab after his death, v. 4. All agree that this was ill done. The Chaldee says, They transgressed the decree of the word of the Lord in taking strange wives. If they would not stay unmarried till their return to the land of Israel, they were not so far off but that they might have fetched themselves wives thence. Little did Elimelech think, when he went to sojourn in Moab, that ever his sons would thus join in affinity with Moabites. But those that bring young people into bad acquaintance, and take them out of the way of public ordinances, though they may think them well-principled and armed against temptation, know not what they do, nor what will be the end thereof. It does not appear that the women they married were proselyted to the Jewish religion, for Orpah is said to return to her gods (v. 15); the gods of Moab were hers still. It is a groundless tradition of the Jews that Ruth was the daughter of Eglon king of Moab, yet the Chaldee paraphrast inserts it; but this and their other tradition, which he inserts likewise, cannot agree, that Boaz who married Ruth was the same with Ibzan, who judged Israel 200 years after Eglon’s death, Jdg. 12.
3. The death of Elimelech and his two sons, and the disconsolate condition Naomi was thereby reduced to. Her husband died (v. 3) and her two sons (v. 5) soon after their marriage, and the Chaldee says, Their days were shortened, because they transgressed the law in marrying strange wives. See here, 1. That wherever we go we cannot out-run death, whose fatal arrows fly in all places. 2. That we cannot expect to prosper when we go out of the way of our duty. He that will save his life by any indirect course shall lose it. 3. That death, when it comes into a family, often makes breach upon breach. One is taken away to prepare another to follow soon after; one is taken away, and that affliction is not duly improved, and therefore God sends another of the same kind. When Naomi had lost her husband she took so much the more complacency and put so much the more confidence in her sons. Under the shadow of these surviving comforts she thinks she shall live among the heathen, and exceedingly glad she was of these gourds; but behold they wither presently, green and growing up in the morning, cut down and dried up before night, buried soon after they were married, for neither of them left any children. So uncertain and transient are all our enjoyments here. It is therefore our wisdom to make sure of those comforts that will be made sure and of which death cannot rob us. But how desolate was the condition, and how disconsolate the spirit, of poor Naomi, when the woman was left of her two sons and her husband! When these two things, loss of children and widowhood, come upon her in a moment, come upon her in their perfection, by whom shall she be comforted? Isa. 47:9; 51:19. It is God alone who has wherewithal to comfort those who are thus cast down.
