It is quite instructive to see that this series of Psalms begins just after the 119th, which, as we know, is the longest and is occupied in the setting forth of the Word of God. There are evidences in this long Psalm that the Word had been let slip, and it had lost its influence on the soul.
Some have thought that the Spirit of God used Ezra to group these Psalms as suitable to their state in journeying from Babylon to Jerusalem, and thus are prophetical of the remnant in the latter days.
