20. for Christ … in Christ's stead—The Greek of both is the same: translate in both cases "on Christ's behalf."
beseech … pray—rather, "entreat [plead with you] … beseech." Such "beseeching" is uncommon in the case of "ambassadors," who generally stand on their dignity (compare 2Co 10:2; 1Th 2:6, 7).
be ye reconciled to God—English Version here inserts "ye," which is not in the original, and which gives the wrong impression, as if it were emphatic thus: God is reconciled to you, be ye reconciled to God. The Greek expresses rather, God was the RECONCILER in Christ … let this reconciliation then have its designed effect. Be reconciled to God, that is, let God reconcile you to Himself (2Co 5:18, 19).
