Acts 4:20

4:20 for it is impossible ¹  for us not to speak about what we have seen and heard.”

Acts 26:20

26:20 but I declared to those in Damascus first, and then to those in Jerusalem and in all Judea, ²  and to the Gentiles, that they should repent and turn to God, ³  performing deeds consistent with ⁴  repentance.

¹ tn Grk “for we are not able not to speak about what we have seen and heard,” but the double negative, which cancels out in English, is emphatic in Greek. The force is captured somewhat by the English translation “it is impossible for us not to speak…” although this is slightly awkward.

² tn BDAG 1093-94 s.v. χώρα 2.b states, “of the provincial name (1 Macc 8:3) ἡ χώρα τῆς ᾿Ιουδαίας Ac 26:20.”

³ sn That they should repent and turn to God. This is the shortest summary of Paul’s message that he preached.

⁴ tn BDAG 93 s.v. ἄξιος 1.b, “καρποὶ ἄ. τῆς μετανοίας fruits in keeping with your repentance…Lk 3:8; Mt 3:8. For this ἄ. τῆς μετανοίας ἔργα Ac 26:20.” Note how Paul preached the gospel offer and the issue of response together, side by side.
