'Lengths' in the Bible

He also defeated the Moabites, and after making them lie down on the ground, he measured them off with a cord. He measured every two cord lengths of those to be put to death and one length of those to be kept alive. So the Moabites became David’s subjects and brought tribute.

Woe to those who go to great lengthsto hide their plans from the Lord.They do their works in darkness,and say, “Who sees us? Who knows us?”

Let no one who delights in humility and the worship of angels pass judgment on you. That person goes on at great lengths about what he has supposedly seen, but he is puffed up with empty notions by his fleshly mind.
