'Arms' in the Bible

So Judas, getting a band of armed men and police from the chief priests and Pharisees, went there with lights and with arms.

"In most solemn truth I tell you that whereas, when you were young, you used to put on your girdle and walk whichever way you chose, when you have grown old you will stretch out your arms and some one else will put a girdle round you and carry you where you have no wish to go."
