Ezra 3:3

And they set the altar upon his bases
Which might remain of the old altar; or the meaning is, that it was fixed and settled on the same spot where it stood before:

for fear was upon them, because of the people of those countries;
and therefore they hastened to erect an altar, and offer sacrifices to the Lord, in hope that he would appear for them, and help them against their enemies; or rather, as some render the words ^F17 "though fear was upon them" yet they were not deterred from the work, worship, and service of God:

and they offered burnt offerings unto the Lord, even burnt offerings,
morning and evening;
the daily sacrifice, as directed to ( Exodus 29:38 Exodus 29:39 ) .
