Matthew Poole and continuators on John 5:21

21 For as the Father raiseth up the dead, and quickneth them , even so the son quickneth whom he will .

He seemeth not to speak of what God will do in the general Resurrection, but of those whom the Lord raised up from the dead in the Old Testament, by Elijah and Elisha. The giving of, and restoring unto Life, are things proper unto God, Deut. 32.39. 1 Sam. 2.6.

So the Son quickneth whom he will. God hath given unto me a Power to raise from the dead whom I will (as he did raise up Iairus his Daughter, Mat. 9.25. and the Widows Son, Luke 7.14. and Lazarus, Chap. 11.43. This was one of those greater works, of which our Saviour spake in the former Verse.
