'Washing' in the Bible

And saw two ships standing by the lake: but the fishermen were gone out of them, and were washing their nets.

And turning to the woman he said to Simon, You see this woman? I came into your house; you did not give me water for my feet: but she has been washing my feet with the drops from her eyes, and drying them with her hair.

When the Pharisee saw this, he was amazed that He did not first perform the ritual washing before dinner.
