Ezra has procured Levites to go along with him; but what will that avail, unless he have God with him? That is therefore his chief care. In all our ways we must acknowledge God, and in those particularly wherein we are endeavouring to serve the interest of his kingdom among men. Ezra does so here. Observe,
I. The stedfast confidence he had in God and in his gracious protection. He told the king (Ezr 8:22) what principles he went upon, that those who seek God are safe under the shadow of his wings, even in their greats dangers, but that those who forsake him are continually exposed, even when they are most secure. God's servants have his power engaged for them; his enemies have it engaged against them. This Ezra believed with his heart, and with his mouth made confession of it before the king; and therefore he was ashamed to ask of the king a convoy, lest thereby he should give occasion to the king, and those about him, to suspect either God's power to help his people or Ezra's confidence in that power. Those that trust in God, and triumph in him, will be ashamed of seeking to the creature for protection, especially of using any sorry shifts for their own safety, because thereby they contradict themselves and their own confidence. Not but that those who depend upon God must use proper means for their preservation, and they need not be ashamed to do so; but, when the honour of God is concerned, one would rather expose one's-self than do any thing to the prejudice of that, which ought to be dearer to us than our lives.
II. The solemn application he made to God in that confidence: He proclaimed a fast, Ezr 8:21. No doubt he had himself begged of God direction in this affair from the first time he had it in his thoughts; but for public mercies public prayers must be made, that all who are to share in the comfort of them may join in the request for them. Their fasting was, 1. To express their humiliation. This he declares to be the intent and meaning of it. "that we might afflict ourselves before our God for our sins, and so be qualified for the pardon of them." When we are entering upon any new condition 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 imminent peril let us be sure to make our peace with God, and then we are safe: nothing can do us any real hurt. 2. To excite their supplications. Prayer was always joined with religious fasting. Their errand to the throne of grace was to seek of God the right way, that is, to commit themselves to the guidance of the divine Providence, to put themselves under the divine protection, and to beg of God to guide and keep them in their journey and bring them safely to their journey's end. They were strangers in the road, were to march through their enemies' countries, and had not a pillar of cloud and fire to lead them, as their fathers had; but they believed that the power and favour of God, and the ministration of his angels, would be to them instead of that, and hoped by prayer to obtain divine assistance. Note, All our concerns about ourselves, our families, and our estates, it is our wisdom and duty by prayer to commit to God, and leave the care of with him, Phi 4:6.
III. The good success of their doing so (Ezr 8:23): We besought our God by joint-prayer, and he was entreated of us. They had some comfortable assurance in their own minds that their prayers were answered, and the event declared it; for never any that sought God in earnest sought him in vain.

I was ashamed to require - a band - He had represented God, the object of his worship, as supremely powerful, and as having the strongest affection for his true followers: he could not, therefore, consistently with his declarations, ask a band of soldiers from the king to protect them on the way, when they were going expressly to rebuild the temple of Jehovah, and restore his worship. He therefore found it necessary to seek the Lord by fasting and prayer, that they might have from Him those succours without which they might become a prey to their enemies; and then the religion which they professed would be considered by the heathen as false and vain. Thus we see that this good man had more anxiety for the glory of God than for his own personal safety.

So we fasted, and besought our God for this,.... Sought the Lord by fasting and prayer for a good journey, and preservation in it:

and he was entreated of us; accepted their prayer, as Jarchi, so that they came safe to Jerusalem.

A FAST PROCLAIMED. (Ezra 8:21-36)

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.
