Psalms 21:4

He asked life of thee, [and] thou gavest [it] him, [even] length of days for ever and ever.

Ver. 4. He asked life of thee] Quando fugiebat a Saule, saith R. Solomon, when he fled from Saul; rather when he went into the field against his enemies, carrying his life in his hand. His life we begged, Psalms 20:1,2, and thou hast not only given him his life, but a long continued series of lives in his successors, 2Sa 7:13 Psalms 72:15, yea, life everlasting in Christ, his Son according to the flesh. See Psalms 61:6. 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.
