Acts 4:29

Lord, behold. The context shows that the prayer of the church is addressed to God the Father. Under the threatenings of the Jewish leaders the apostles were not disheartened, but drew nearer to the God who could aid them in whatever danger they faced. The threats of the Jews were ultimately directed against God (see on ch. 9:4, 5).

Servants. Gr. douloi, “slaves.”

Boldness. Gr. parresia (see on v. 13). The apostles had shown “boldness of speech” before the Sanhedrin (v. 13), and now their prayer, as though showing consciousness of natural weakness, is for a yet further bestowal of that gift of courage (see Luke 21:15). They realized it was now needed more than ever, for both themselves and the entire church.

Speak thy word. It is not enough that the godly life be lived by the Christian, as a testimony to the power of Christ. The doctrine of salvation in Jesus Christ must also be given utterance (see Rom. 10:13-17).
