Numbers 29:12

On the fifteenth day of the seventh month - On this day there was to be a solemn assembly, and for seven days sacrifices were to be offered; on the first day thirteen young bullocks, two rams, and fourteen lambs. On each succeeding day one bullock less, till on the seventh day there were only seven, making in all seventy. What an expensive service! How should we magnify God for being delivered from it! Yet these were all the taxes they had to pay. At the public charge there were annually offered to God, independently of trespass-offerings and voluntary vows, fifteen goats, twenty-one kids, seventy-two rams, one hundred and thirty-two bullocks, and eleven hundred and one lambs! But how little is all this when compared with the lambs slain every year at the passover, which amounted in one year to the immense number of 255,600 slain in the temple itself, which was the answer that Cestius, the Roman general, received when he asked the priests how many persons had come to Jerusalem at their annual festivals; the priests, numbering the people by the lambs that had been slain, said, "twenty-five myriads, five thousand and six hundred." - For an account of the feast of tabernacles, see on Leviticus 23:34 (note).

Feast of tabernacles: compare Leviticus 23:33 ff. The offerings required at this feast were the largest of all. It was especially one of thankfulness to God for the gift of the fruits of the earth; and the quantity and the nature of the offerings (see Numbers 29:7-11) were determined accordingly.

29:12 Seven days - Not by abstaining so long from all servile work, but by offering extraordinary sacrifices each day. This was the Feast of Tabernacles. And all the days of their dwelling in booths, they must offer sacrifices. While we are in these tabernacles, 'tis our interest as well as duty, to keep up our communion with God. Nor will the unsettledness of our outward condition, excuse our neglect of God's worship.
