1. A call to praise Yahweh 29:1-2

The phrase "sons of the mighty"(NASB) or "mighty ones"(NIV) probably refers to the angels. The Old Testament writers called Israel God's son, but they did not refer to individual believers that way. The idea that every believer is God's son was revelation Jesus Christ introduced for the first time (Matt. 6:9; et al.).

These verses are an excellent example of climactic parallelism. In climactic parallelism the writer makes a statement and every time he repeats the same idea in a succeeding line he does so more forcefully. Holy array was the dress morally more than physically with which the Israelites were to worship God when they assembled for their national festivals at the sanctuary.
