They have almost consumed me upon the earth. He repeats, in somewhat different words, what he had spoken a little before, that, although he had been sorely tempted, he had nevertheless kept his footing, because he had not given up with true religion. A single declaration of this fact would have been enough for those who are perfect; but if we call to mind our own weakness, we will readily confess that it was not unworthy of being repeatedly stated. We not only forget the law of God when we are shaken by extreme conflicts, but the greater part lose their courage even before they engage in the conflict. On which account this wonderful strength of the prophet is worthy of more special notice, who, although almost reduced to death, yet never ceased to revive his courage by continual meditation on the law. Nor is it in vain that he adds, that it was upon the earth that his enemies had almost consumed him, conveying the idea, that, when the fears of death presented themselves to him on all sides in this world, he elevated his mind above the world. If faith reach to heaven, it will be an easy matter to emerge from despair.

They had almost consumed me upon earth - The word which is here translated "consumed" is the same which is used in Psalm 119:81, and there rendered "fainteth." See the notes at that verse. The idea is, that their persecutions had been so severe, and so long continued, that his strength was almost exhausted; he was ready to faint and to die.
But I forsook not thy precepts - I still adhered to thee, even in the extremity of my suffering. The effect of persecution was not to drive me from thee, or to lead me to abandon thee. See Psalm 119:61, note; Psalm 119:69, note.

They had almost consumed me - Had it not been for thy mercy, we had all been destroyed under this oppressive captivity.

They had almost consumed (f) me upon earth; but I forsook not thy precepts.
(f) Finding no help on earth, he lifts up his eyes to heaven.

They had almost consumed me upon earth,.... Almost destroyed his good name, wasted his substance, took away his crown and kingdom, and even his life; it was within a little of it, his soul had almost dwelt in silence; they had almost cast him down to the ground, and left him there. But all this was only on earth; they could not reach any thing that belonged to him in heaven; not his name, which was written there in the Lamb's book of life; nor his riches and inheritance there, the never fading crown of glory laid up for him there; or that eternal life, which is hid with Christ in God for him;
but I forsook not thy precepts; did not decline the service and worship of God, nor neglect his word and ordinances, though thus persecuted, and all these things came upon him for the sake of religion; see Psalm 44:17.

consumed me upon earth--HENGSTENBERG translates, "in the land"; understanding "me" of the nation Israel, of which but a small remnant was left. But English Version is simpler; either, "They have consumed me so as to leave almost nothing of me on earth"; or, "They have almost destroyed and prostrated me on the earth" [MAURER].
I forsook not--Whatever else I am forsaken of, I forsake not Thy precepts, and so am not mistaken of Thee (Psalm 39:5, Psalm 39:13; 2-Corinthians 4:8-9), and the injuries and insults of the wicked increase the need for it. But, however they act regardless of God's law, the pious, adhering to its teaching, receive quickening grace, and are sustained steadfast.
