المزامير ٤٠:١

David, who, though not without some hesitation, we regard as the author, now finds himself in a situation in which, on the one hand, he has just been rescued from danger, and, on the other, is still exposed to peril. Under such circumstances praise rightly occupies the first place, as in general, according to Psa 50:23, gratitude is the way to salvation. His hope, although תּוחלת ממשּׁכה (Pro 13:12), has not deceived him; he is rescued, and can now again sing a new song of thanksgiving, an example for others, strengthening their trust. קוּה קוּיתי, I waited with constancy and perseverance. יהוה is the accusative as in Psa 25:5; Psa 130:5, and not the vocative as in Psa 39:8. אזנו is to be supplied in thought to ויּט, although after the analogy of Psa 17:6; Psa 31:3, one might have looked for the Hiph. wayaT instead of the Kal. בור שׁאון does not mean a pit of roaring (of water), since שׁאון standing alone (see, on the other hand, Psa 65:8, Isa 17:12.) has not this meaning; and, moreover, "rushing, roaring" (Hengstenberg), tumultuous waters of a pit or a cistern does not furnish any idea that is true to nature; neither does it mean a pit of falling in, since שׁאה does not exhibit the signification deorsum labi; but the meaning is: a pit of devastation, of destruction, of ruin (Jer 25:31; Jer 46:17), vid., supra on Psa 35:8. Another figure is "mire of the marsh" (יון found only here and in Psa 69:3), i.e., water, in the miry bottom of which one can find no firm footing - a combination like מטר־גּשׁם, Zac 10:1, אדמת־עפר, Dan 12:2, explained in the Mishna, Mikvaoth ix. 2, by טיט הבורות (mire of the cisterns). Taking them out of this, Jahve placed his feet upon a rock, established his footsteps, i.e., removed him from the danger which surrounded him, and gave him firm ground…

In these verses we have, I. The great distress and trouble that the psalmist had been in. He had been plunged into a horrible pit and into miry clay (Psa 40:2), out of which he could not work himself, and in which he found himself sinking yet further. He says nothing here either of the sickness of his body or the insults of his enemies, and therefore we have reason to think it was some inward disquiet and perplexity of spirit that was now his greatest grievance. Despondency of spirit under the sense of Gods withdrawings, and prevailing doubts and fears about the eternal state, are indeed a horrible pit and miry clay, and have been so to many a dear child of God. II. His humble attendance upon God and his believing expectations from him in those depths: I waited patiently for the Lord, Psa 40:1. Waiting, I waited. He expected relief from no other than from God; the same hand that tears must heal, that smites must bind up (Hos 6:1), or it will never be done. From God he expected relief, and he was big with expectation, not doubting but it would come in due time. There is power enough in God to help the weakest, and grace enough in God to help the unworthiest, of all his people that trust in him. But he waited patiently, which intimates that the relief did not come quickly; yet he doubted not but it would come, and resolved to continue believing, and hoping, and praying, till it did come. Those whose expectation is from God may wait with assurance, but must wait with patience. Now this is very applicable to Christ. His agony, both in the garden and on the cross, was the same continued, and it was a horrible pit and miry clay. Then was his soul troubled and exceedingly sorrowful; but then he prayed, Father, glorify thy name; Father, save me; then he kept hold of his relatio…

Ps 40 This psalm includes a thanksgiving song (40:1-10) followed by a lament (40:11-17). The thanksgiving song includes the reason for the thanksgiving (40:1-5), an affirmation of commitment (40:6-8), and a public testimony of God’s character (40:7-10). The lament concerns the psalmist’s troubles because of his sins (40:11-12) and is followed by two prayers for vindication (40:13-15, 17). 40:1-5 The psalmist thanks the Lord for his rescue and testifies that God can be trusted.
