Matthew Poole and continuators on 2 Kings 2:10

10 And he said, Thou hast asked a hard thing : nevertheless, if thou see me when I am taken from thee, it shall be so unto thee: but if not, it shall not be so .

i. e. A rare and singular Blessing, which I cannot promise thee, which onely God can give; and he gives it onely when, and to whom he pleaseth.

This Sign he proposed, not without the instinct and direction of God's Spirit, that hereby he might engage him more earnestly to wait, and more fervently to pray for this mercy.

Marginal references: Heb. Thou hast done hard in asking.
