Commentary on the Bible, by Adam Clarke, [1831], at sacred-texts.com
The month of Abib to be observed, Deu 16:1. The feast of the passover and of unleavened bread, Deu 16:2-8. The feast of weeks, Deu 16:9-12. The feast of tabernacles, Deu 16:13-15. All the males to appear before the Lord thrice in the year, none to come empty, each to give according to his ability, Deu 16:16, Deu 16:17. Judges and officers to be made in all their cities, Deu 16:18. Strict justice shall be executed, Deu 16:19, Deu 16:20. No grove to be planted near the altar of God, nor any image to be set up, Deu 16:21, Deu 16:22.
Keep the passover - A feast so called because the angel that destroyed the firstborn of the Egyptians, seeing the blood of the appointed sacrifice sprinkled on the lintels and door-posts of the Israelites' houses, passed over Them, and did not destroy any of their firstborn. See the notes on Exo 12:2, and Exo 12:3 (note), etc.
Bread of affliction - Because, being baked without leaven, it was unsavoury, and put them in mind of their afflictive bondage in Egypt.
Thou shalt rejoice - The offerings of the Israelites were to be eaten with festivity, communicated to their friends with liberality, and bestowed on the poor with great generosity, that they might partake with them in these repasts with joy before the Lord. To answer these views it was necessary to eat the flesh while it was fresh, as in that climate putrefaction soon took place; therefore they were commanded to let nothing remain until the morning, Deu 16:4. This consideration is sufficient to account for the command here, without having recourse to those moral and evangelical reasons that are assigned by the learned and devout Mr.
Ainsworth for the command. How beneficent and cheerful is the design of this institution! - Harmer, vol. i., p. 396.
Three times in a year - See Exo 23:14 (note), where all the Jewish feasts are explained. See also Lev 23:34 (note).
Judges and officers shalt thou make - Judges, שפטים shophetim, among the Hebrews, were probably the same as our magistrates or justices of the peace. Officers, שטרים shoterim, seem to have been the same as our inquest sergeants, beadles, etc., whose office it was to go into the houses, shops, etc., and examine weights, measures, and the civil conduct of the people. When they found any thing amiss, they brought the person offending before the magistrate, and he was punished by the officer on the spot. They seem also to have acted as heralds in the army, Deu 20:5. See also Rab. Maimon in Sanhedrin. In China, for all minor offenses, the person when found guilty is punished on the spot, in the presence of the magistrate or mandarin of justice.
Thou shalt not plant thee a grove, etc. - We have already seen that groves were planted about idol temples for the purpose of the obscene worship performed in them. (See on Deu 12:3 (note)). On this account God would have no groves or thickets about his altar, that there might be no room for suspicion that any thing contrary to the strictest purity was transacted there. Every part of the Divine worship was publicly performed, for the purpose of general edification.
