For a thousand years in thy sight are but as yesterday
Which may be said to obviate the difficulty in man's return, or resurrection, from the dead, taken from the length of time in which some have continued in the grave; which vanishes, when it is observed, that in thy sight, esteem, and account of God, a thousand years are but as one day; and therefore, should a man lie in the grave six or seven thousand years, it would be but as so many days with God; wherefore, if the resurrection is not incredible, as it is not, length of time can be no objection to it. Just in the same manner is this phrase used by the Apostle Peter, and who is thought to refer to this passage, to remove an objection against the second coming of Christ, taken from the continuance of things as they had been from the beginning, and from the time of the promise of it: see ( 2 Peter 3:4-8 ) , though the words aptly express the disproportion there is between the eternal God and mortal man; for, was he to live a thousand years, which no man ever did, yet this would be as yesterday with God, with whom eternity itself is but a day, ( Isaiah 43:13 ) , man is but of yesterday, that has lived the longest; and were he to live a thousand years, and that twice told, it would be but "as yesterday when it is past"; though it may seem a long time to come, yet when it is gone it is as nothing, and can never be fetched back again:
and as a watch in the night;
which was divided sometimes into three, and sometimes into four parts, and so consisted but of three or four hours; and which, being in the night, is spent in sleep; so that, when a man wakes, it is but as a moment with him; so short is human life, even the longest, in the account of God; (See Gill on Matthew 14:25).
