'Worship God' in the Bible

It happened that as David [was] coming up to the summit where he used to worship God, suddenly Hushai the Arkite [was] there to meet him. His coat [was] torn and dirt [was] on his head.

saying, "This man is persuading people to worship God contrary to the law!"

the secret things of his heart become evident, and so, falling on [his] face, he will worship God, proclaiming, "God is truly among you!"

And I fell down before his feet to worship him, and he said to me, "{Do not do that!} I am a fellow slave of you and of your brothers who hold to the testimony of Jesus. Worship God! For the testimony of Jesus is the spirit of prophecy."

And he said to me, "{Do not do that!} I am your fellow slave, and of your brothers the prophets, and of those who keep the words of this book. Worship God!"
