Verse 84. — How many are the days of thy servant? When will thou execute judgement on them that persecute me?; Isaiah 16:14. The Psalmist does not, then, bewail in general the transitory life of man, but he complains that the time of his state of warfare in this world had been too long protracted; and, therefore, he naturally desires that it might be brought to a termination. In expostulating with God about his troubles, he does not do so obstinately, or with a murmuring spirit; but still, in asking how long it will be necessary for him to suffer, he humbly prays that God would not delay to succour him. — John Calvin.
