Commentary
10 notes on this verseMy knees are weak through fasting,..... Either voluntary or forced, through want of food or refreshment; this was verified in Christ, when he kneeled and prayed, and his sweat was as it were great drops of blood falling to the ground; see Psa 69:10. And my flesh faileth of fatness; or "for want of oil" (k); the radical moisture of his flesh being dried up like a potsherd, Psa 22:15. (k) משמן δι' ελαιον, Sept. "propter oleum", V. L. "propter defectum olei", Eth. Arab.

like a lengthening shadow
on Psalms 109:23-25
Three pictures stand together, a lengthening shadow, a locust shaken off, and knees weak from fasting. The body grows lean and gaunt. The accusers see him and shake their heads, the gesture the mockers make at Psalm 22:7.

And thus also thou canst shew that all the righteous men and Prophets, either by their own will, or by God's command unto them, endured always tribulations and labours, even as the blessed David maketh known that from the severity of his fasting the very …
My knees are weakened from fasting. Take consolation, O monk, in fasting: since the Lord too did this. I say that when a monk fasts, he becomes stronger through fasting; and when his knees are weakened by fasting, then he is most of all strengthened. And my flesh is changed on account of oil. I seem to be saying a difficult thing, and I interpret it according to the letter, that I may edify my hearers: for even the letter edifies me. It is good to fast, it is good to flee from delicacies.
"I became also a reproach unto them" [Psalm 109:24]: through the death of the Cross. "For Christ has redeemed us from the curse of the law, being made a curse for us." [Galatians 3:13] "They looked upon Me, and shaked their heads." Because they beheld His crucifixion, without beholding His resurrection: they saw when His knees were weakened, they saw not when His flesh was changed.

): My knees are weak through fasting, either forced fasting (for want of food when he was persecuted, or for want of appetite when he was sick) or voluntary fasting, when he chastened his soul either for sin or affliction, his own or other's, Ps. xxxv.

My knees are weak through fasting; either religious fasting, to which he resorted in the dire extremity of his grief, or else through loss of appetite occasioned by distress of mind. Who can eat when every morsel is soured by envy? This is the advantage of the slanderer, that he feels nothing himself, while his sensitive victim can scarcely eat a morsel of bread because of his sensitiveness. However, the good God knoweth all this, and will succour his afflicted. The Lord who bids us confirm the feeble knees will assuredly do it himself. "And my flesh faileth of fatness."

He was wasted to a skeleton, and as his body was emaciated, so was his soul bereft of comfort: he was pining away, and all the while his enemies saw it and laughed at his distress. How pathetically he states his case; this is one of the truest forms of prayer, the setting forth of our sorrow before the Lord. Weak knees are strong with God, and failing flesh has great power in pleading.
My knees are weak through fasting - That hunger is as soon felt in weakening the knees, as in producing an uneasy sensation in the stomach, is known by all who have ever felt it. Writers in all countries have referred to this effect of hunger. Thus Tryphioderus Il. Excid. ver 155: Τειρομενου βαρυθειεν ατερπεΐ γουνατα λιμῳ. “Their knees might fail, by hunger’s force subdued; And sink, unable to sustain their load.” Merrick. So Plautus, Curcul, act. ii., scen. 3: - Tenebrae oboriuntur, genua inedia succidunt. “My eyes grow dim; my knees are weak with hunger.” And Lucretius, lib. 4: ver. 950: - Brachia, palpebraeque cadunt, poplitesque procumbunt. “The arms, the eyelids fall; the knees give way.” Both the knees and the sight are particularly affected by hunger.

My knees are weak through fasting - Hunger; want of food. Strength to stand is connected with firmness in the knee-joints, and hence, weakness and feebleness are denoted by the giving way of the knees. Compare Heb 12:12. And my flesh faileth of fatness - I am lean and weak. There is not the proper supply for my strength. The idea seems to have been that fatness (Hebrew, oil) was necessary to strength.
