Praise the Lord! Praise the Lord from the heavens; praise him in the heights! Praise him, all his angels; praise him, all his host! Praise him, sun and moon; praise him, all you shining stars!Praise him, you highest heavens, and you waters above the heavens! Let them praise the name of the Lord, for he commanded and they were created. He established them for ever and ever; he fixed their bounds, which cannot be passed. (Psalm 148: 1-6)

We are to boast about God. We are to brag about God. In Middle English boast is closely related to brag. Originally brag was an adjective not a verb. Something was brag when it was exceptionally fine. God is very brag.

We are to praise God. The Hebrew is halal which can also be to act madly or as a fool. We are to fall madly in love with God. We are to lose our senses, even lose ourselves in our love for God. We are to receive God's love with abandon.

Halal also means to shine or flash. We are to demonstrate our love for God and confidence in God in how we conduct ourselves. We should be as mirrors reflecting heavenly light. In us others should perceive the light of God.
