'Thigh' in the Bible

Abraham said to his servant, the elder of his household who managed all he owned, “Place your hand under my thigh,

So the servant placed his hand under his master Abraham’s thigh and swore an oath to him concerning this matter.

That is why, to this day, the Israelites don’t eat the thigh muscle that is at the hip socket: because He struck Jacob’s hip socket at the thigh muscle.

When the time drew near for him to die, he called his son Joseph and said to him, “If I have found favor in your eyes, put your hand under my thigh and promise me that you will deal with me in kindness and faithfulness. Do not bury me in Egypt.
