To me the passage from 2 Cor 1:18-22 for 7 OT Sunday B reads like a rough draft rather than a finished translation, especially verses 19 and 20:
Brothers and sisters:
As God is faithful,
our word to you is not “yes” and “no.”
For the Son of God, Jesus Christ,
who was proclaimed to you by us, Silvanus and Timothy and me,
was not “yes” and “no, “ but “yes” has been in him.
For however many are the promises of God, their Yes is in him;
therefore, the Amen from us also goes through him to God for glory.
But the one who gives us security with you in Christ
and who anointed us is God;
he has also put his seal upon us
and given the Spirit in our hearts as a first installment.
Yes, the Greek original is “lumpy”:
πιστὸς δὲ ὁ θεὸς ὅτι ὁ λόγος ἡμῶν ὁ πρὸς ὑμᾶς οὐκ ἔστιν ναὶ καὶ οὔ
ὁ τοῦ θεοῦ γὰρ υἱὸς Ἰησοῦς Χριστὸς ὁ ἐν ὑμῖν δι’ ἡμῶν κηρυχθείς δι’ ἐμοῦ καὶ Σιλουανοῦ καὶ Τιμοθέου οὐκ ἐγένετο ναὶ καὶ οὔ ἀλλὰ ναὶ ἐν αὐτῷ γέγονεν
ὅσαι γὰρ ἐπαγγελίαι θεοῦ ἐν αὐτῷ τὸ ναί διὸ καὶ δι’ αὐτοῦ τὸ ἀμὴν τῷ θεῷ πρὸς δόξαν δι’ ἡμῶν
ὁ δὲ βεβαιῶν ἡμᾶς σὺν ὑμῖν εἰς Χριστὸν καὶ χρίσας ἡμᾶς θεός
ὁ καὶ σφραγισάμενος ἡμᾶς καὶ δοὺς τὸν ἀρραβῶνα τοῦ πνεύματος ἐν ταῖς καρδίαις ἡμῶν
Can we use the Anchor Bible version or the Contemporary English Version?
2 Cor 1:18-22/ Victor Paul Furnish
18 As God is faithful, our word to you is not both yes and no. 19 For the Son of God, Jesus Christ, who was preached among you by us—by myself, and also by Silvanus and Timothy—was not “Yes” and “No.” Rather, in him it has been an enduring “Yes.” 20 All the promises of God have their Yes in him; hence, through him as well as through us the “Amen” glorifies God. 21 The one who is confirming us along with you in Christ and anointed us is God, 22 who also sealed us and gave the Spirit as a down payment in our hearts.
2 Cor 1:18-22/ CEV
18 God can be trusted, and so can I, when I say that our answer to you has always been “Yes” and never “No.”
19 This is because Jesus Christ the Son of God is always “Yes” and never “No.” And he is the one that Silas, Timothy, and I told you about.
20 Christ says “Yes” to all of God’s promises. That’s why we have Christ to say “Amen” for us to the glory of God.
21 And so God makes it possible for you and us to stand firmly together with Christ. God is also the one who chose us
22 and put his Spirit in our hearts to show that we belong only to him.
