Acts 12:2-5

Living_Oracles(i) 2 And he slew James, the brother of John, with the sword. 3 And as he saw that this was acceptable to the Jews, he went on to seize Peter also: and it was in the days of unleavened bread; 4 and having seized him, he put him in prison, delivering him to the custody of four quaternions of soldiers, intending, after the passover, to bring him out to the people. 5 In the meantime, therefore, Peter was kept in the prison; but earnest and continued prayer was made to God on his account, by the congregation.
