'Worship' in the Bible

At this, David got up from the ground, washed, anointed himself, changed his clothes, and went into the LORD's tent to worship. Then he went back to his palace where, at his request, they served him food and he ate.

For your servant made a vow when I lived in Geshur of Aram, saying: If the Lord really brings me back to Jerusalem, I will worship the Lord in Hebron.”

When David came to the summit where he used to worship God, Hushai the Archite was there to meet him with his robe torn and dust on his head.
