'Knees' in the Bible

When they had returned to the people, there came to Him a man who fell on his knees before Him and besought Him.

One day there came a leper to Jesus entreating Him, and pleading on his knees. "If you are willing," he said, "you are able to cleanse me."

Then they began to beat Him on the head with a cane, to spit on Him, and to do Him homage on bended knees.

When Simon Peter saw this, he fell down at the knees of Jesus, and exclaimed, "Master, leave my boat, for I am a sinful man."

At one place where He was praying, when He rose from His knees one of His disciples said to Him, "Master, teach us to pray, just as John taught his disciples."

Then, rising on his knees, he cried aloud, "Lord, do not reckon this sin against them." And with these words he fell asleep.

Therefore strengthen the drooping hands and paralysed knees,
