Commentaries
3:1-7 From the proceedings of the Jews on their arrival, let us learn to begin with God, and to do what we can in the worship of God, when we cannot do what we would. They could not at once have a temple, but they would not be without an altar. Fear of danger should stir us to our duty. Have we many enemies? Then it is good to have God our Friend, and to keep up communion with him. Our fears should drive us to our knees. The sacrifices for all these solemnities were a heavy expense for so poor a company; yet besides those expressly appointed, many brought free-will offerings to the Lord. And they made preparation for the building of the temple without delay: whatever God calls us to do, we may depend upon his providence to furnish us with the needful means.
3. they set the altar upon his bases—They reared it upon its old foundation, so that it occupied as nearly as possible the site on which it had formerly stood.
they offered burnt offerings … morning and evening—Deeming it their duty to perform the public rites of religion, they did not wait till the temple should be rebuilt and dedicated; but, at the outset, they resumed the daily service prescribed by the law (Ex 29:38, 39; Le 6:9, 11), as well as observed the annual seasons of solemn observance.
