These verses introduce the whole passion narrative. Passover commemorated the Israelites' redemption from slavery in Egypt through the Exodus (Exod. 12:1-13:16). It anticipated a greater deliverance from the consequences of slavery to sin. The Jews began to celebrate Passover on the fourteenth of Nisan, and the feast of Unleavened Bread followed on the fifteenth through the twenty-first of Nisan. Mark dated the events that follow immediately as occurring two days before Passover. This would have been Wednesday, April 1, 33 A.D.330
Passover, like the feasts of Tabernacles and Pentecost, was a pilgrim feast. Many Jewish families from all over the world travelled to Jerusalem to observe these feasts as the Mosaic Law required (Deut. 16:16). The Jews could observe the Passover only in Jerusalem (Deut. 16:5-6). Consequently mobs of people choked the city. Jesus enjoyed a large popular following, so the religious leaders wanted to avoid a riot by executing Jesus inconspicuously. Evidently they wanted to postpone further confrontation with Jesus until after the feasts when the pilgrims would have returned to their homes. However, Judas' offer to betray Jesus (vv. 10-11) was too good to refuse.
