Ezra 10:4

Arise
From the ground, where he lay prostrate:

for this matter belongeth unto thee;
as a priest and scribe of the law, well versed in it, and therefore could direct what was to be done according to it; and as a ruler under the king of Persia, and a commissioner of his, to inquire whether the law of God was observed by the Jews, ( Ezra 7:14 ) and so had authority to put the law in execution:

we also will be with thee;
to help and assist in the reformation of this evil:

be of good courage, and do it;
do not despair of going through it, though there may be some opposition to it; begin, and doubt not of succeeding.
