'Weakness' in the Bible

In the manner of men I speak, because of the weakness of your flesh, for even as ye did present your members servants to the uncleanness and to the lawlessness -- to the lawlessness, so now present your members servants to the righteousness -- to sanctification,

because the foolishness of God is wiser than men, and the weakness of God is stronger than men;

and I, in weakness, and in fear, and in much trembling, was with you;

it is sown in dishonour, it is raised in glory; it is sown in weakness, it is raised in power;

for a disannulling indeed doth come of the command going before because of its weakness, and unprofitableness,
