Are in the night when a holy solemnity is kept: he mentions the night, either because the Jewish feasts begun at the evening, and were celebrated with great joy in part of the night season, as well as on the following day; or because he hath a particular respect to the solemnity of the passover, in which they spent some considerable part of the night in feasting, and rejoicing, and singing of psalms and songs before the Lord. As when one goeth with a pipe; like the joy of one that is going up to the solemn feasts with music, and the voice of joy and praise, as they used to do, Psalms 42:4, to cheer up themselves in the way, which to many of them was long, and would otherwise have been tedious.
