Matthew 26:20

Verse 20. When the even was come. The lamb was killed between the evenings, Ex 12:6, (Hebrew) that is, between three o'clock P.M. and nine in the evening. The Jews reckoned two evenings, one from three o'clock P.M. to sunset, the other from sunset to the close of the first watch in the night, or nine o'clock. The paschal supper was commonly eaten after the setting of the sun, and often in the night, Ex 12:8. He sat down. At first, the supper was eaten standing, with the loins girded and their staff in their hand, denoting the haste with which they were about to flee from Egypt.
