“Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.”
King James Version (KJV)
22:36 But now - You will be quite in another situation. You will want every thing. He that hath no sword, let him sell his garment and buy one - It is plain, this is not to be taken literally. It only means, This will be a time of extreme danger.
Lu 22:36 But now. Now has come a time of trial when all will be against you. He that hath no sword, let him . . . buy one. Not to be taken literally, but a striking way of saying that enemies upon every side will assail them.
