Ezra 3:1

When the seventh month was come We may suppose they left Babylon in the spring, and were four months on their journey; for so long Ezra and his company were in coming, Ezra 7:9. The seventh month therefore commenced soon after their arrival in Judea, when, as many of the feasts of the Lord were then to be solemnized, the people gathered themselves together By agreement among themselves, rather than by the command of authority; to Jerusalem Though they were newly come to their cities, and had their hands full of business there, to provide necessaries for themselves and their families, which might have excused them from attending on God's worship in public, till the hurry was a little over, as many with us foolishly put off their coming to the communion till they are settled in the world; yet, such was their zeal for religion, now they were newly come from under correction for their irreligion, that they left all their business in the country to attend God's altar; and in this pious zeal they were all of a mind, they came as one man.
