13:4 Yahweh had been Israel's God since the Israelites had lived in Egypt.83He had commanded the Israelites not to acknowledge any gods beside Himself because He was the only God who could save them (cf. Deut. 11:28; 32:17; Jer. 9:2; 31:34). For them to become idolaters would only be frustrating and futile. To abandon the only savior is to doom oneself to no salvation.
13:5 The Lord also was the one who cared for the Israelites in the wilderness and who kept them alive in that barren wasteland. His provisions of manna and water are only two examples.
13:6 When they entered the Promised Land and began to enjoy rich pastures, they soon became self-satisfied, proud, and forgot their God. Prosperity is often a greater temptation to depart from conscious dependence on God than adversity is, and Israel fell into this trap.
13:7-8 In view of Israel's behavior, the Lord promised to become as an enemy of His people, like a lion or leopard that laid in wait to attack a sheep grazing in rich pasture (v. 6). He would confront them as a mother bear crazed by the loss of her cubs (cf. 2 Sam. 17:8; Prov. 17:12). He would tear them open like a bear and consume them like a lioness. The lion, leopard, and bear were all wild animals native to Canaan that were notorious for their relentless manner of killing prey.
