“I will praise Thee with my whole heart: before the gods will I sing praise unto Thee.” Psalm 138:1 (KJV)
The Psalmist, David, does not even mention His name. He feels no need to; anymore than a child standing before their father feels a need to call the man they adore by name. “Thee”, or “You” is all that he needs to say.
Jehovah is the One of whom he speaks, because David addressed no other. The nations around worshipped many gods; but David only one. Many gods were put to shame by Jehovah as He delivered Israel from Egypt (Exodus 12:12). All the Egyptian gods were shown to be powerless; because idols require the strength of their makers.
It is with stretched out hands and arms, and with music David praised the LORD. There is no other worthy of praise. Let us with heart, hands, tongue, mind, voice and music always praise the LORD.
Let that praise begin through believing in the Lord Jesus Christ. The only place it can truly begin.
