This psalm, it is likely, was penned upon the same occasion with the former, and, having no title, may be looked upon as an appendix to it; the malady presently returning, he had immediate recourse to the same remedy, because he had entered it in his book, with a "probatum est - it has been proved," upon it. The second verse of this psalm is almost the very same with the ninth verse of the foregoing psalm, as the fifth of this is exactly the same with the eleventh of that. Christ himself, who had the Spirit without measure, when there was occasion prayed a second and third time "saying the same words," Mat 26:44. In this psalm. I. David appeals to God concerning the injuries that were done him by his enemies (Psa 43:1, Psa 43:2). II. He prays to God to restore to him the free enjoyment of public ordinances again, and promises to make a good improvement of them (Psa 43:3, Psa 43:4). III. He endeavours to still the tumult of his own spirit with a lively hope and confidence in God (Psa 43:5), and if, in singing this psalm, we labour after these, we sing with grace in our hearts.
