2 Corinthians 1:21

ὁ δὲ βεβαιῶν κ. τ. λ.: now He that stablisheth us with you into Christ and anointed us is God, etc. For the form of the sentence cf. chap. 2 Corinthians 5:5. The ultimate ground of St. Paul's steadfastness in Christ is God Himself; and having been led on to say this, he adds σὺν ὑμῖν, in order to introduce (as he does at every opportunity in the early part of the Epistle) the idea of unity between him and his Corinthian converts. The play on words Χριστόν … χρίσας is obvious; the only other place in the N.T. where the idea is found of the “anointing” of the Christian believer by God is 1 John 2:20; 1 John 2:27, ὑμεῖς χρίσμα ἔχετε ἀπὸ τοῦ ἁγίου. Deissmann has pointed out (Bibelstudien, p. 104) that βεβαιόω and ἀρραβών (see note below) are both technical terms belonging to the law courts (cf. Leviticus 25:23, LXX), and that βεβαιῶν is here deliberately used rather than κυριῶν (Galatians 3:15), or any other such word.
