God is often referred to as a Shepherd in the Old Testament (cf. Ps. 23:1; Jer. 23:1-4; Ezek. 34:11-12,23). It is a metaphor used of to speak of God as the primary caregiver and leader of Israel, His covenant people. Consequently, Micah petitions God on behalf of the remnant. The expectation of the entreaty is that Yahweh would restore the nations blessings. This insight can be drawn from the symbolic reference to Bashan and Gilead. Historically, these regions were known for as there agricultural fertility.
15 As in the days when you came out of the land of Egypt, I will show them marvelous things.
God responds with a promise that He will act on the remnants behalf. He would effect the nation’s “release from impending captivity,” just as He did their Exodus from Egyptian oppression. Beyond the most obvious historical import of the Egypt allusion, the prophet’s emphasis is that God is almighty, sovereign over all nations, and loved His covenant people. The nation could find comfort in the knowledge that the exile from the Promised Land would not be permanent.
