This first part of chapter 6 envisions Israel's repentance. The prophet predicted the words that the penitent generation of Israelites would say when they sought the Lord (5:15). The message contains two cycles, each containing an exhortation (vv. 1a, 3a) and a motivating promise (vv. 1b-2, 3b).48
6:1 The repentant Israelites would encourage each other to return to Yahweh because they believed He would heal them (as a shepherd, cf. 5:13) even though He had torn and wounded them (as a lion, cf. 5:14). They would recognize that their punishment had come from Him, not just from a foreign enemy (cf. Deut. 32:39).
6:2 He would revive them after a relatively brief period of judgment (two days; cf. Job 5:19; Prov. 6:16; 30:15, 18; Amos 1:3, 6, 9, et al.) and restore them to life and usefulness.49He would do this so they might enjoy His fellowship and serve Him.
6:3 Such a hope would motivate this revived generation of Israelites to encourage themselves to pursue intensely knowing (acknowledging) Yahweh as the true God and as their God (cf. 4:1, 6; 5:4). They would be confident of His restoration because of His character, His faithfulness to His promises (e.g., 5:15), and His power. His return to bless them would be as certain and as life-giving as the sunrise. He would bring refreshment and fertility back to the nation (cf. Deut. 11:13-15). No more would they look to Baal for these blessings.
Israel has never prayed like this. The fulfillment must still be future, at the beginning of Christ's millennial reign.
