Galatians 4:13
But you are aware [I am sure] that when I first came preaching the Gospel [message] to you, I had a physical handicap.
1 Corinthians 2:3
And I was weak, apprehensive and fearful when I was [there] with you. [Note: This probably refers to Paul's sense of inadequacy in view of the task before him].
Galatians 1:6
I am astonished that you people are so quickly abandoning God [i.e., by rejecting His truth], who called you [to Himself] through the unearned favor bestowed [on us] by Christ. [You are turning] to a different "gospel,"
Acts 16:6
And then Paul, Silas, Timothy [and perhaps others by now] traveled through the districts of Phrygia and Galatia [i.e., provinces of central Asia Minor] because [an inspired message from] the Holy Spirit would not permit them to proclaim the message in Asia [i.e., the westernmost province of Asia Minor].
2 Corinthians 10:10
For some people are saying, "Paul's letters are heavy and severe, but in person he is [physically?] weak and his speaking ability is unimpressive."
2 Corinthians 11:6
But even though I am an unpolished speaker, I am not lacking in knowledge. We have made this clear to you in every way.
2 Corinthians 11:30
If I must boast, I will boast about the things that show my weakness.
2 Corinthians 12:7-10
But, so that I would not become too conceited over the tremendous revelations [I received], a "thorn in the flesh" was given to me as a messenger from Satan to torment me. [Note: This "thorn" was probably some physical handicap, possibly defective eyesight. See Gal. 4:14-15; 6:11].
2 Corinthians 13:4
For He was weak when He was crucified [i.e., by assuming a human body capable of suffering and death], but [now] He lives by God's power. For we too are weak, [along] with Him [i.e., each of us experiences the frailties of a human body], but by [this same] power from God, we will live with Him to serve you. [Note: The various translations differ widely on how to properly translate this difficult verse].
