Daniel 2:18

That they would desire mercies of the God of heaven concerning this secret,....

They desired mercy concerning this secret. Note, Whatever is the matter of our care must be the matter of our prayer; we must desire mercy of God concerning this thing and the other thing that occasions us trouble and fear. God gives us leave to be humbly free with him, and in prayer to enter into the detail of our wants and burdens.

That they would desire mercies - For this Daniel had requested a little time; and doubtless both he and his three companions prayed incessantly till God gave the wished for revelation; but whether it was given that same sight, we do not know.

That they would desire mercies of the God of heaven concerning this secret - That they would implore of God that he would show his mercy to them in revealing this secret, that their lives might be spared. In the margin, as in the Chaldee, this is “from before the God of heaven.” All depended now on God. It was clear that human skill was exhausted, and that no reliance could be placed on any ability which man possessed. The art of the Chaldeans had failed, and Daniel, as well by this failure as by the promptings of his own feelings, must now have perceived that the only hope was in God, and that his favor in the case was to be obtained only by prayer. As his three friends were equally interested in the issue, and as it was an early principle of religion, and one found in all dispensations (compare Mat 18:19), that “united” prayer has special power with God, it was natural and proper to call on his friends to join with him in asking this favor from Him who alone could grant it. It was the natural and the last resource of piety, furnishing an example of what all may do, and should do, in times of perplexity and danger. That Daniel and his fellows should not perish - Margin, “or, they should not destroy Daniel.” The leading in the margin is most in accordance with the Chaldee, though the sense is substantially the same. The word “fellows” is the same which is before rendered “companions.” With the rest of the wise men of Babylon - It seems to have been certain that the decree would be executed on the Chaldeans, soothsayers, etc. And, indeed, there was no reason “why” the decree should not be executed. They had confessed their inability to comply with the king’s command, and whatever Daniel could now do could not be construed in their favor as furnishing any reason why the decree should not be executed on them.
