And when they had taken {c} security of Jason, and of the other, they let them go.

(c) When Jason had put them in good assurance that they would appear.

People's New Testament

17:9 When they had taken security. Of those asserted. They received some kind of guarantee that there would be nothing done contrary to the laws of the empire.

Jamieson-Fausset-Brown Bible Commentary

9. And when they had taken security of Jason and of the other-"the others"-probably making them deposit a money pledge that the preachers should not again endanger the public peace.

Matthew Henry's Concise Commentary

17:1-9 The drift and scope of Paul's preaching and arguing, was to prove that Jesus is the Christ. He must needs suffer for us, because he could not otherwise purchase our redemption for us; and he must needs have risen again, because he could not otherwise apply the redemption to us. We are to preach concerning Jesus that he is Christ; therefore we may hope to be saved by him, and are bound to be ruled by him. The unbelieving Jews were angry, because the apostles preached to the Gentiles, that they might be saved. How strange it is, that men should grudge others the privileges they will not themselves accept! Neither rulers nor people need be troubled at the increase of real Christians, even though turbulent spirits should make religion the pretext for evil designs. Of such let us beware, from such let us withdraw, that we may show a desire to act aright in society, while we claim our right to worship God according to our consciences.
