From verses 3-7 Habakkuk highlighted the splendour of God to remind the Israelites of his power to discipline them and defeat their enemy, the Babylonians.
Habakkuk described the action of God against the Babylonians as him coming from Teman and Mount Paran. These were the areas through which the children of Israel travelled when they were in the wilderness on their way to the Promised Land. God was with them on this journey, therefore these two places were a reminder to them that as he had previously led and directed them, he would again come to deliver them from their enemy. The word selah
causes the reader to pause and think about the significance of God being with his people on their wilderness travels. Therefore, God coming from Teman and Mount Paran was to assure them that just as he was present with them in the wilderness, he would be at their side during the suffering they would have to experience from the Babylonians.
His splendour that covered the heavens described his glory which he would reveal when he came to deliver his people. The consequence of God displaying himself in this way would be that the earth would be full of praise. The Israelites would rejoice in being assured that God would come to their rescue by displaying his power against the Babylonians. Through what he was to do for them, he would reveal his greatness showing that there was nothing nor anyone to compare with him and who was able to resist his strength.
3 God came from Teman, and the Holy One from Mount Paran. Selah His splendor covered the heavens, and the earth was full of his praise.
