Philippians 3:3
For we [Christians] are the [true] circumcision [i.e., the real "Jews" in God's eyes. See Rom. 2:28-29].

Hebrews 2:17
So, for this reason, He had to become like His brothers in every way [i.e., except that He never sinned], so that He could become a merciful and faithful Head Priest in things related to God's [service], [and] that He could provide a means of purifying [Lev. 16:30] for people's sins [i.e., make atonement for them].

Again I say, no one should think I am foolish, but if you do, [then] accept me that way, so that I too can boast a little bit.
2 Corinthians 12:1
Although I must boast about myself [See 11:21-27], it [really] is not profitable. So, I will go on to [tell about] visions and [inspired] revelations given [to me] from the Lord.
2 Corinthians 12:11-21
I have become foolish [i.e., by my boasting], but you made me do it [i.e., in order to vindicate myself]. For I should have been commended by you [i.e., for my effective ministry there in Corinth], because I was not inferior in any way to those "super apostles" [See 11:5], even though I am nothing.
