2 Corinthians 10:10-18 King James Version (KJV)
10 For his letters, say they, are weighty and powerful; but his bodily presence is weak, and his speech contemptible.
11 Let such an one think this, that, such as we are in word by letters when we are absent, such will we be also in deed when we are present.
12 For we dare not make ourselves of the number, or compare ourselves with some that commend themselves: but they measuring themselves by themselves, and comparing themselves among themselves, are not wise.
13 But we will not boast of things without our measure, but according to the measure of the rule which God hath distributed to us, a measure to reach even unto you.
14 For we stretch not ourselves beyond our measure, as though we reached not unto you: for we are come as far as to you also in preaching the gospel of Christ:
15 Not boasting of things without our measure, that is, of other men's labours; but having hope, when your faith is increased, that we shall be enlarged by you according to our rule abundantly,
16 To preach the gospel in the regions beyond you, and not to boast in another man's line of things made ready to our hand.
17 But he that glorieth, let him glory in the Lord.
18 For not he that commendeth himself is approved, but whom the Lord commendeth.
