'Knees' in the Bible

For Solomon had made a brasen scaffold, of five cubits long, and five cubits broad, and three cubits high, and had set it in the midst of the court: and upon it he stood, and kneeled down upon his knees before all the congregation of Israel, and spread forth his hands toward heaven,

When all the Israelites saw the fire come down and the Lord's splendor over the temple, they got on their knees with their faces downward toward the pavement. They worshiped and gave thanks to the Lord, saying, "Certainly he is good; certainly his loyal love endures!"
