'Weaknesses' in the Bible

But [in fact] He has borne our griefs,And He has carried our sorrows and pains;Yet we [ignorantly] assumed that He was stricken,Struck down by God and degraded and humiliated [by Him].

so that He fulfilled what was spoken by the prophet Isaiah: “He Himself took our infirmities [upon Himself] and carried away our diseases.”

On behalf of such a man [and his experiences] I will boast; but in my own behalf I will not boast, except in regard to my weaknesses.

but He has said to me, “My grace is sufficient for you [My lovingkindness and My mercy are more than enough—always available—regardless of the situation]; for [My] power is being perfected [and is completed and shows itself most effectively] in [your] weakness.” Therefore, I will all the more gladly boast in my weaknesses, so that the power of Christ [may completely enfold me and] may dwell in me.

For we do not have a High Priest who is unable to sympathize and understand our weaknesses and temptations, but One who has been tempted [knowing exactly how it feels to be human] in every respect as we are, yet without [committing any] sin.
