2 Corinthians 10:13

But we will not boast of things without our measure. This is the second charge brought by S. Paul against the false Apostles. They boast so largely that one would think they have preached the Gospel in every part of the world (Theophylact). I, however, boast not falsely, or beyond my measure; I measure myself by the true measure of the gifts and provinces that God has marked out for me. This measure reaches from Judæa through the intervening countries to Corinth. Just as kings glory in having extended their realms far and wide, so do I, as a doctor sent by Christ, glory in having extended His sway, and I hope to extend it still further.

Rule here denotes the measuring-line used by surveyors to fix the boundaries of fields and other grounds (cf. ver. 16). Measure denotes (1.) that by which anything is measured, as a yard-measure or a foot-measure; (2.) it denotes the quantity of the measuring-line; and (3.) the act of measuring; (4.) it stands for the thing measured, a bushel of wheat or an acre of land; i.e., corn to the amount of a bushel, land to the amount of an acre. In any of these last three senses the word may be used here, but best of all in the second.
