Theophylact of Ohrid

On the tenth day of the month they took the lamb which was to be sacrificed on the passover, and from that time began the preparation for the feast. Or rather the ninth day of the month, i. e. six days before the passover, was the commencement of the feast. They feasted abundantly on that day. Thus we find Jesus partook of a banquet at Bethany: There they made Him a supper, and Martha served. That Martha served, shews that the entertainment was in her house. See the fidelity of the woman: she does not leave the task of serving to the domestics, but takes it upon herself. The Evangelist adds, in order, it would seem, to settle Lazarus’ resurrection beyond dispute, But Lazarus was one of them that sat at the table with Him.
