'Kneeling' in the Bible

When they came to the multitude, a man came to him, kneeling down to him, saying,

Then the mother of the sons of Zebedee came to him with her sons, kneeling and asking a certain thing of him.

A leper came to him, begging him, kneeling down to him, and saying to him, "If you want to, you can make me clean."

When it happened that we had accomplished the days, we departed and went on our journey. They all, with wives and children, brought us on our way until we were out of the city. Kneeling down on the beach, we prayed.
