Verse 7. - In the day of my trouble I will call upon thee (comp. vers. 1 and 14). The nature of the trouble is not distinctly stated; but it appears to have been caused by domestic rather than foreign enemies. For thou wilt answer me (comp. ver. 5).

86:1-7 Our poverty and wretchedness, when felt, powerfully plead in our behalf at the throne of grace. The best self-preservation is to commit ourselves to God's keeping. I am one whom thou favourest, hast set apart for thyself, and made partaker of sanctifying grace. It is a great encouragement to prayer, to feel that we have received the converting grace of God, have learned to trust in him, and to be his servants. We may expect comfort from God, when we keep up our communion with God. God's goodness appears in two things, in giving and forgiving. Whatever others do, let us call upon God, and commit our case to him; we shall not seek in vain.In the day of my trouble I will call upon thee,.... David had his troubles, both inward and outward, before and after he came to the throne, in private and public life; and every good man has his troubles; and there are some particular times or days of trouble; which trouble arises from different causes; sometimes from themselves, their corruptions, the weakness of their grace, and the poor performance of their duties; sometimes from others; from the persecutions of the men of the world; from the wicked lives of profane sinners, and especially professors of religion, and from the spread of false doctrine; sometimes from Satan and his temptations; and sometimes from the more immediate hand of God in afflictions, and from the hidings of his face: these troubles do not last always; they are but for a day, for a particular time; and such a season is a fit one for prayer, and the Lord invites and encourages his people to call upon him in prayer when this is the case, Psalm 50:15. Christ had his times of trouble, in which he called upon his divine Father, John 11:33.

for thou wilt answer me; which the idols of the Gentiles could not do; Baal could not answer his priests, 1 Kings 18:26, this the psalmist concluded, both from the promise of God, Psalm 50:15, and from his frequent experience, Psalm 138:3, a very encouraging reason or argument this to call on the Lord: Christ was always heard and answered, John 11:41.
