Psalm 91:16

16 I shall [ful]fill him with the length of days; and I shall show mine health to him. (I shall fulfill him with length of days, that is, with a long life; and I shall give my salvation, or my deliverance, to him/and I shall save him.)

Psalm 91:16 Meaning and Commentary

Psalms 91:16

With long life will I satisfy him
In this world: the saints live in it as long as they choose to live; and when they come to die, be it when it will, they are, like Abraham, full of years, or satisfied with them; they have had enough of them, and would not live always here; but, with good old Simeon, desire to depart in peace; and in the other world they shall be satisfied with length of days, for ever and ever, even with eternal life; and nothing short of this will satisfy a good man:

and show him my salvation;
Jesus Christ, the author of salvation, whom God appointed to do it, and who has finished it; salvation itself, wrought out by him; its fulness and suitableness, and interest in it; and also eternal glory and happiness, the completion and consummation of salvation: the former is shown unto and seen by faith here; the latter will be seen and enjoyed in heaven to all eternity. Aben Ezra and Kimchi refer this salvation to the days of the Messiah.

Psalm 91:16 In-Context

14 (For God saith,) For he hoped in me, I shall deliver him (For God saith, Because he loved me, I shall save him); I shall defend him, for he knew my name.

15 He cried to me, and I shall hear him; I am with him in tribulation; I shall deliver him, and I shall glorify him. (When he crieth to me, I shall answer him; I shall be with him in all his troubles; I shall rescue him, and I shall honour him.)

16 I shall [ful]fill him with the length of days; and I shall show mine health to him. (I shall fulfill him with length of days, that is, with a long life; and I shall give my salvation, or my deliverance, to him/and I shall save him.)
