'Weaken' in the Bible

O Lord, do not Your eyes look for truth?You have smitten them,But they did not weaken;You have consumed them,But they refused to take correction.They have made their faces harder than rock;They have refused to repent.

And the princes said unto the king, Let this man, we pray thee, be put to death; for why should he weaken the hands of the men of war that remain in this city, and the hands of all the people, in speaking to them according to these words? for this man seeketh not the welfare of this people, but the hurt.
