The Lord brought a legal charge against the Israelites for breaking the Mosaic Covenant. Again the literary form of this section is a legal confrontation (Heb. rib, cf. 2:2). The Lord stated His charges against Israel in 4:1-3 and then developed these charges in reverse order.
4:1 Hosea called on the Israelites to listen to a word from Yahweh because He was charging them with serious crimes. Yahweh was taking the Israelites to court. The basic accusation is that there was no faithfulness (truth, trustworthiness), kindness (loyalty, Heb. hesed), or (evidence of) knowledge of God in the land. The Israelites failed to acknowledge Yahweh as their God (cf. 2:20). These were all things that God had ordered His people to pursue when He covenanted with them at Sinai.
4:2 Instead of these virtues, He observed swearing (cursing others), deception, murder, stealing, adultery, violence, and continual bloodshed. These were things He had forbidden in His covenant. He identified violations of at least five of the Ten Commandments (numbers 3, 9, 6, 8, and 7). Violent crimes were so common that they seemed to follow one another without interruption.
4:3 Therefore God was not blessing Israel but was bringing curses on the land so every part of the Northern Kingdom suffered, every living thing. Drought seems to be the particular form of chastisement in view (cf. Lev. 26:19; Deut. 28:23-24).
