As regards Holy-days, there is the general rule that work (‏מלאכה‎) prohibited on Sabbath must not be done on Holy-days: “Save that which every man must eat, that only may be done of you” (Exod. xii. 16); that is to say, it is allowed on Festivals to cook, to bake, or to prepare food in any other way. [66] Of course, for the Festival that happens to fall on a Sabbath, the laws of Sabbath remain in force. The Day of Atonement is in this respect equal to Sabbath. c. ‏ענג‎ “Delight.” The principal and noblest delight yielded by Holy-days is the pleasure we feel in more frequent communion with the Divine Being, in the purer and holier thoughts with which we are inspired when at rest from ordinary work, and able to devote ourselves more fully to the contemplation of the works and words of God. In this sense the day of rest is described in one of the hymns (‏זמירות‎) after supper as “a foretaste of the world to come” (‏מעין עולם הבא יום שבת מנוחה‎). But oneg shabbath includes also delight of a less spiritual character. We are not commanded on the days of rest to forget altogether the wants of the body. On the contrary. Nehemiah, when on the first day of the seventh month, that is, on New-year, he perceived that his brethren were sad, addressed them thus: “Go your way, eat the fat and drink the sweet, and send portions unto him for whom nothing is prepared: for this day is holy unto the Lord: neither be ye grieved; for the joy of the Lord is your strength” (Neh. viii. 10). The same conception of “the sabbath unto the Lord” is met with in Talmud, Midrash, and throughout the whole of the Rabbinical literature. In one of our Sabbath-hymns (‏זמירות‎) we say: “This day is for Israel, light and joy, a sabbath of rest;” and in our prayers for Sabbath we glory in being shom’re shabbath ve-kor’e oneg, “observers of the sabbath, and such as call it a delight.”—With regard to the Festivals, the duty of rejoicing is repeatedly enjoined (Deut. xvi. 11, 14). In our regulations, customs, and prayers for Sabbath and Festivals, this duty is clearly indicated. All fasting and mourning is prohibited. Care was taken that Divine Service should be free from such prayers as would be likely to create feelings of grief and sadness. [67] A special formula has also been introduced for the expression of our sympathy with the sick and the mourner on Sabbath and Festivals. [68]
