Then I proclaimed a fast there, at the river of Ahava, that we might afflict {f} ourselves before our God, to seek of him a right way for us, and for our little ones, and for all our substance.

(f) He shows that the purpose of fasting is to humble the body to the spirit, which must proceed from the heart that is touched, or else it is hypocrisy.

Wesley's Notes

8:21 A fast - For public mercies. Publick prayers must be made, that all who are to share in the comfort, may share in the requests for it. Afflict ourselves - For our sins; and so be qualified for the pardon of them. When we are entering on any new condition of life, our care should be to bring into it none of the guilt of the sins of our former condition. When we are in any imminent danger, let us make our peace with God, and then nothing can hurt us. Right way - A safe and prosperous journey; such a way and course as might be best for us.

Jamieson-Fausset-Brown Bible Commentary

Ezr 8:21-36. A Fast Proclaimed.

21. Then I proclaimed a fast there-The dangers to travelling caravans from the Bedouin Arabs that prowl through the desert were in ancient times as great as they still are; and it seems that travellers usually sought the protection of a military escort. But Ezra had spoken so much to the king of the sufficiency of the divine care of His people that he would have blushed to apply for a guard of soldiers. Therefore he resolved that his followers should, by a solemn act of fasting and prayer, commit themselves to the Keeper of Israel. Their faith, considering the many and constant perils of a journey across the Bedouin regions, must have been great, and it was rewarded by the enjoyment of perfect safety during the whole way.

Matthew Henry's Concise Commentary

8:21-23 Ezra procured Levites to go with him; but what will that avail, unless he have God with him? Those who seek God, are safe under the shadow of his wings, even in their greatest dangers; but those who forsake him, are always exposed. When entering upon any new state of life, our care should be, to bring none of the guilt of the sins of our former condition into it. When we are in any peril, let us be at peace with God, and then nothing can do us any real hurt. All our concerns about ourselves, our families, and our estates, it is our wisdom and duty, by prayer to commit to God, and to leave the care of them with him. And, on some occasions, we should decline advantages which are within our reach, lest we should cause others to stumble, and so our God be dishonoured. Let us ask wisdom of God, that we may know how to use or to refuse lawful things. We shall be no losers by venturing, suffering, or giving up for the Lord's sake. Their prayers were answered, and the event declared it. Never have any that sought God in earnest, found that they sought him in vain. In times of difficulty and danger, to set a season apart for secret or for social prayer, is the best method for relief we can take.
