'Knees' in the Bible

So he brought down the people to the water; and Yahweh said to Gideon, "Everyone who laps of the water with his tongue, like a dog laps, you shall set him by himself; likewise everyone who bows down on his knees to drink."

The number of those who lapped, putting their hand to their mouth, was three hundred men; but all the rest of the people bowed down on their knees to drink water.

She made him sleep on her knees; and she called for a man, and shaved off the seven locks of his head; and she began to afflict him, and his strength went from him.
