'Thigh' in the Bible

Abraham said to his servant [Eliezer of Damascus], the oldest of his household, who had charge over all that Abraham owned, “Please, put your hand under my thigh [as is customary for affirming a solemn oath],

So the servant put his hand under the thigh of Abraham his master, and swore to him concerning this matter.

When the Man saw that He had not prevailed against Jacob, He touched his hip joint; and Jacob’s hip was dislocated as he wrestled with Him.

Now the sun rose on him as he passed Penuel (Peniel), and he was limping because of his hip.
