Habakkuk 3:7

Habakkuk saw the semi-nomadic Ethiopians and Midianites, who lived on both sides of Mt. Sinai, trembling with fear because they witnessed something of Yahweh’s power. The terms Midianite and Cushite both described Moses’ wife (Exodus 2:16-22; Exodus 18:1-5; Numbers 12:1), so they may be synonyms here. Perhaps this is a reference to Yahweh parting the Red Sea. It is small wonder that these tribes trembled since His glance can cause mountains to melt (Habakkuk 3:6).
