'Weakness' in the Bible

If I have to boast, I will boast of what pertains to my weakness.

And He has said to me, “My grace is sufficient for you, for power is perfected in weakness.” Most gladly, therefore, I will rather boast about my weaknesses, so that the power of Christ may dwell in me.

For indeed He was crucified because of weakness, yet He lives because of the power of God. For we also are weak in Him, yet we will live with Him because of the power of God directed toward you.
