(17) Three times in the year.—The terms of this verse, as compared with Exodus 23:14, limit the observance of the three festivals to the males, but add the important requirement of personal attendance at a given place. By “all thy males” we must understand all of full age and not incapacitated by infirmity or illness.

Exodus 23:17. All thy males — All that were of competent years, and health, and strength, and at their own disposal. It is probable, servants were exempt: for none was to appear without an offering: but most of these had nothing to offer.

23:10-19 Every seventh year the land was to rest. They must not plough or sow it; what the earth produced of itself, should be eaten, and not laid up. This law seems to have been intended to teach dependence on Providence, and God's faithfulness in sending the larger increase while they kept his appointments. It was also typical of the heavenly rest, when all earthly labours, cares, and interests shall cease for ever. All respect to the gods of the heathen is strictly forbidden. Since idolatry was a sin to which the Israelites leaned, they must blot out the remembrance of the gods of the heathen. Solemn religious attendance on God, in the place which he should choose, is strictly required. They must come together before the Lord. What a good Master do we serve, who has made it our duty to rejoice before him! Let us devote with pleasure to the service of God that portion of our time which he requires, and count his sabbaths and ordinances to be a feast unto our souls. They were not to come empty-handed; so now, we must not come to worship God empty-hearted; our souls must be filled with holy desires toward him, and dedications of ourselves to him; for with such sacrifices God is well pleased.In the end of the year - Compare Exodus 34:22. The year here spoken of must have been the civil or agrarian year, which began after harvest, when the ground was prepared for sowing. Compare Leviticus 23:39; Deuteronomy 16:13-15. The sacred year began in spring, with the month Abib, or Nisan. See Exodus 12:2 note, and Leviticus 25:9.

When thou hast gathered - Rather, when thou gatherest in.

14-18. Three times … keep a feast … in the year—This was the institution of the great religious festivals—"The feast of unleavened bread," or the passover—"the feast of harvest," or pentecost—"the feast of ingathering," or the feast of tabernacles, which was a memorial of the dwelling in booths in the wilderness, and which was observed in the seventh month (Ex 12:2). All the males were enjoined to repair to the tabernacle and afterwards the temple, and the women frequently went. The institution of this national custom was of the greatest importance in many ways: by keeping up a national sense of religion and a public uniformity in worship, by creating a bond of unity, and also by promoting internal commerce among the people. Though the absence of all the males at these three festivals left the country defenseless, a special promise was given of divine protection, and no incursion of enemies was ever permitted to happen on those occasions. To wit, such as are of competent years, and health, and strength, and such as were at their own dispose; for that servants were not bound to this may seem probable, because none of these concerned were to appear before the Lord empty, or without an offering, but the generality of servants had not any thing to offer. And the care and management of their domestic affairs did require the presence and care of many of their males.

Before the Lord God, i.e. in that place where God shall record his name, Exodus 20:24, as the tabernacle or temple.

Three times in the year all thy males shall appear before the Lord thy God. In the city of Jerusalem, when they were come into the land of Canaan, and the temple was there built: here they were to show themselves before the Lord as being his, and devoted to his service; concerning which the Misnic doctors have the following canon (c),"all are bound to appear except a man deaf and dumb, a fool, a little one, one of neither sex, or of both sexes, women, servants not free, the lame, the blind, the sick, an old man, and he that cannot go on his feet.''

(c) Misn. Chagigah, c. 1. sect. 1.

Three times in the year all thy males shall appear before the LORD God.
