'Loins' in the Bible

The young men who grew up with him spoke to him, saying, “Thus you shall say to this people who spoke to you, saying, ‘Your father made our yoke heavy, now you make it lighter for us!’ But you shall speak to them, ‘My little finger is thicker than my father’s loins!

Then the hand of the Lord was on Elijah, and he girded up his loins and outran Ahab to Jezreel.

His servants said to him, “Behold now, we have heard that the kings of the house of Israel are merciful kings, please let us put sackcloth on our loins and ropes on our heads, and go out to the king of Israel; perhaps he will save your life.”

So they girded sackcloth on their loins and put ropes on their heads, and came to the king of Israel and said, “Your servant Ben-hadad says, ‘Please let me live.’” And he said, “Is he still alive? He is my brother.”
