'Feeble' in the Bible

But be you strong and let not your hands be feeble, for your work will be rewarded.

And those men who have been named went up and took the prisoners, clothing those among them who were uncovered, with things from the goods which had been taken in the war, and putting robes on them and shoes on their feet; and they gave them food and drink and oil for their bodies, and seating all the feeble among them on asses, they took them to Jericho, the town of palm-trees, to their people, and then went back to Samaria.
