'Feebler' in the Bible

But when the cattle were feeble, he put them not in: so the feebler were Laban's, and the stronger Jacob's.

For which cause we do not give way to weariness; but though our outer man is getting feebler, our inner man is made new day by day.

And you husbands, give thought to your way of life with your wives, giving honour to the woman who is the feebler vessel, but who has an equal part in the heritage of the grace of life; so that you may not be kept from prayer.
