from the reading חגּינוּ, which, following the lxx and the best texts, is to be rejected in comparison with the singular חגּנוּ. If, however, it is to be read chgnw, and כּסה (according to Kimchi with Segol not merely in the second syllable, but with double Segol כּסה, after the form טנא = טנא) signifies not interlunium, but plenilunium (instead of which also Jerome has in medio mense, and in Pro 7:20, in die plenae lunae, Aquila ἡμέρᾳ πανσελήνου), then what is meant is either the Feast of Tabernacles, which is called absolutely החג in 1Ki 8:2 (2Ch 5:3) and elsewhere, or the Passover, which is also so called in Isa 30:29 and elsewhere. Here, as Psa 81:5 will convince us, the latter is intended, the Feast of unleavened bread, the porch of which, so to speak, is ערב פּסח together with the ליל שׁמּרים (Exo 12:42), the night from the fourteenth to the fifteenth of Nisan. In Psa 81:2, Psa 81:3 they are called upon to give a welcome to this feast. The blowing of the shophar is to announce the commencement of the Passover month, and at the commencement of the Passover day which opens the Feast of unleavened bread it is to be renewed. The ל of ליום is not meant temporally, as perhaps in Job 21:30 : at the day = on the day; for why was it not ביום? It is rather: towards the day, but בכסה assumes that the day has already arrived; it is the same Lamed as in Psa 81:2, the blowing of the shophar is to concern this feast-day, it is to sound in honour of it.
Verses 4-5
Psa 81:4-5 now tell whence the feast which is to be met with singing and music has acquired such a high significance: it is a divine institution coming from the time of the redemption by the hand of Moses. It is called חק as being a legally sanctioned decree, משׁפּט as being a lawfully binding appointment, and עדוּת as being a positive declaration of the divine will. The ל in לישׂראל characterizes Israel as the receiver, in לאלהי the God of Israel as the owner, i.e., Author and Lawgiver. By בּצעתו the establishing of the statute is dated back to the time of the Exodus; but the statement of the time of its being established, “when He went out over the land of Egypt,” cannot be understood of the Exodus of the people out of Egypt, natural as this may be here, where Israel has just been called יהוסף (pathetic for יוסף), by a comparison with Gen 41:45, where Joseph is spoken of in the same words. For this expression does not describe the going forth out of a country, perhaps in the
