Psalms 120:7

This psalm is the first of those fifteen which are here put together under the title of "songs of degrees." It is well that it is not material what the meaning of that title should be, for nothing is offered towards the explication of it, no, not by the Jewish writers themselves, but what is conjectural. These psalms do not seem to be composed all by the same hand, much less all at the same time. Four of them are expressly ascribed to David, and one is said to be designed for Solomon, and perhaps penned by him; yet 126 and 129 seem to be of a much later date. Some of them are calculated for the closet (as 120 and 130), some for the family (as 127 and 128), some for the public assembly (as 122 and 134), and some occasional, as 124, and 132. So that it should seem, they had not this title from the author, but from the publisher. Some conjecture that they are so called from their singular excellency (as the song of songs, so the song of degrees, is a most excellent song, in the highest degree), others from the tune they were set to, or the musical instruments they were sung to, or the raising of the voice in singing them. Some think they were sung on the fifteen steps or stairs, by which they went up from the outward court of the temple to the inner, others at so many stages of the people's journey, when they returned out of captivity. I shall only observe, 1. That they are all short psalms, all but one very short (three of them have but three verses apiece), and that they are placed next to Ps. 119, which is by much the longest of all. Now as that was one psalm divided into many parts, so these were many psalms, which, being short, were sometimes sung all together, and made, as it were, one psalm, observing only a pause between each; as many steps make one pair of stairs.…
