'Sapped' in the Bible

And they came and besieged him in Abel-Beth-Maacah, and they cast up a bank against the city, and it was raised in the trench; and all the people that were with Joab sapped the wall, to throw it down.

For day and night your hand was heavy on me. My strength was sapped in the heat of summer. Selah.

(Nun) My sins are bound around my neck like a yoke; they are fastened together by his hand. He has placed his yoke on my neck; he has sapped my strength. The Lord has handed me over to those whom I cannot resist.
