John Lightfoot on Matthew 9:24

[The maid is not dead, but sleepeth.] It was very ordinary among them to express the death of any one by the word which properly signifies to sleep. When N. slept; that is, when he died: a phrase to be met with hundreds of times in the Talmudists. And this whole company would say, The daughter of Jairus sleeps; that is, she is dead. Therefore it is worthy considering what form of speech Christ here used. The Syriac hath, She is not dead, but asleep.
