'Knees' in the Bible

(For Solomon had made a brass stage, five cubits long, five cubits wide and three cubits high, and had put it in the middle of the open space; on this he took his place and went down on his knees before all the meeting of Israel, stretching out his hands to heaven.)

And all the children of Israel were looking on when the fire came down, and the glory of the Lord was on the house; and they went down on their knees, with their faces to the earth, worshipping and praising the Lord, and saying, He is good; for his mercy is unchanging for ever.
