My knees are weak through fasting; and my flesh faileth of fatness.
Ver. 24. My knees are weak through fasting] Either for lack of meat or stomach to it; genua labant, my knees buckle under me, the strong men bow themselves, Ecclesiastes 12:3 .
My flesh faileth of fatness] I am lean and low brought. Christ might well cry out, "My leanness, my leanness"; so busy he was for his Father, and so worn out, that they judged him well nigh fifty, when he was not much over thirty, John 8:57 .
