Charles H. Spurgeon on Psalms 21:4

"He asked life of thee," etc. Thus God is better to his people than their prayers; and when they ask but one blessing, he answereth them as Naaman did Gehazi, with, Nay, take two. Hezekiah asked but one life, and God gave him fifteen years, which we reckon at two lives and more. He giveth liberally and like himself; as great Alexander did when he gave the poor beggar a city; and when he sent his schoolmaster a ship full of frankincense, and bade him sacrifice freely. —John Trapp.
