I am taken away like the shadow when it declineth: and I am shaken off as locusts.

“"My knees are weak through fasting" (ver. 23). We read, that our Lord Christ underwent a fast of forty days: but had fasting so great power over Him, that His knees were weakened? Or is this more suitably understood of His members, that is, of His saints? "And my flesh is changed because of the oil;" because of spiritual grace, Whence Christ was so called from the Greek word, chrisma, which signifies unction. But the flesh was changed through the oil, not for the worse, but for the better, that is, rising from the dishonour of death to the glory of immortality. ...His flesh was not yet changed. But whether the Holy Spirit be represented by water through the notion of ablution or irrigation, or by oil through that of exultation and the inflaming of charity; It doth not differ from Itself, because Its types are different. For there is a great difference between the lion and the lamb, and yet Christ is represented by both. ...”

“My 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) , Sept. "propter oleum", V. L. "propter defectum olei", Eth. Arab.”
