Now at [that] feast,.... The Syriac, Arabic, and Ethiopic versions read, "at every feast": which looks as if the authors of these versions thought the sense was, that the following custom was used at each feast in the year, at the feasts of pentecost, and tabernacles, and passover; whereas it was only at the feast of the passover; and which is meant by the feast here, as is clear fromJoh 18:39.
It was but once a year that this was done; at every returning passover; and so the Persic version renders it, "every year on the day of the feast"; that is, of the passover, and which was frequently called by way of emphasis, gx, "the feast":the governor was wont to release unto the people a prisoner, whom they would.
It was not a law, but a custom; it was not enjoined by the law of Moses; for they that sinned against that; died without mercy: nor is it agreeable to strict justice, that there should be such a release of criminals; nor was it a Jewish custom, as an emblem of their deliverance out of Egyptian bondage.
