A.T. Robertson Commentary Acts 4:29

"And now, Lord, look upon their threatenings: and grant unto thy servants to speak thy word with all boldness," — Acts 4:29 (ASV)

And now (κα τα νυν). "And as to (accusative of general reference) the now things (the present situation)." Only in the Acts in the N.T. (5:38; 17:30; 20:32; 27:22).

Grant (δος). Second aorist active imperative of διδωμ, urgency of the aorist, Do it now.

To speak thy word with all boldness (μετα παρρησιας πασης λαλειν τον λογον σου). Literally, "with all boldness to go on speaking (present active infinitive) thy word." Peter and John had defied the Sanhedrin in verse 20, but all the same and all the more they pray for courage in deed to live up to their brave words. A wholesome lesson.
