In preparation for the first Pesach (Passover), God commanded the Hebrews to select a lamb for each family on the tenth day of the month of Nissan (April 14). Each family was to keep their lamb for four days, naturally becoming attached to the adorable animal. This selection process became known as Sabbath HaGadol, the Sabbath before Passover. (Exodus 12)
Many centuries later, as recorded by the prophet Daniel, God said there would be 490 years, from the time the command was given by Darus (445 BC) to rebuild the Jewish Temple, (which had been destroyed by the Babylonians), to when the Messiah would come. (Daniel 9:24-25)
The Messiah did indeed come on the scheduled date, the tenth of Nissan.
As prophesied in Zechariah 9:9, Yeshua rides into Jerusalem on the back of a donkey, to present Himself to the Jewish people as their Messiah and Lamb. (Matthew 21:5)
Most of the people did not recognize Him. Do we recognize Him as the Lamb who was sacrificed for our sins?
In thankfulness to Him!
