Charles H. Spurgeon on Psalms 119:147

And cried. Here is a repetition of the same prayer, "I cried"; yea, again I cried, and a third time, "I prevented the dawning of the morning, and cried." We use to knock at a door thrice, and then depart. Our Lord Jesus "prayed the third time, saying the same words" (Matthew 26:44), "Father, if it he possible, let this cup pass from me." So the apostle Paul: "For this thing I besought the Lord thrice, that it might depart from me": 2 Corinthians 12:8. So, "And he stretched himself upon the child three times, and cried unto the Lord, and said, O Lord my God, I pray thee, let this child's soul come into him again": 1 Kings 17:21. This, it seemeth, was the time in which they expected an answer in weighty cases; and yet I will not confine it to that number; for here we are to reiterate our petitions for one and the same thing as often as occasion requireth, till it be granted. Thomas Manton.
