'Weak' in the Bible

because the letters indeed -- saith one -- are weighty and strong, and the bodily presence weak, and the speech despicable.'

in reference to dishonour I speak, how that we were weak, and in whatever any one is bold -- in foolishness I say it -- I also am bold.

for even if he was crucified from infirmity, yet he doth live from the power of God; for we also are weak in him, but we shall live with him from the power of God toward you.
