'Weaker' in the Bible

After this, a state of protracted war existed between Saul's dynasty and David's dynasty, and the dynasty of David continued to grow and become strong while the dynasty of Saul continued to grow weaker.

The fishermen will groan, and all who cast hooks into the Nile will lament; those who spread nets upon the water will become weaker and weaker.

since you've been bumping aside all the weaker sheep with your backsides and shoulders, butting them with your horns until they're scattered around outside.
