All thy males - Old men, sick men, male idiots, and male children under thirteen years of age, excepted; for so the Jewish doctors understand this command.

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" (i.e., according to Exodus 23:14 and Deuteronomy 16:16, at the three feasts just mentioned) "all thy males shall appear before the face of the Lord Jehovah." The command to appear, i.e., to make a pilgrimage to the sanctuary, was restricted to the male members of the nation, probably to those above 20 years of age, who had been included in the census (Numbers 1:3). But this did not prohibit the inclusion of women and boys (cf. 1-Samuel 1:3., and Luke 2:31.).

All thy males - All that were of competent years, and health and strength, and at their own disposal. 'Tis probable, servants were exempt: for none was to appear without an offering: but most of these had nothing to offer.
