And they found written in the law which the Lord had commanded
 by Moses
 The children of Israel, to be observed by them; either by hearing it read the day before, or by conversation with Ezra, they perceived it was enjoined in the law, particularly in ( Leviticus 23:39-43 ) ( Deuteronomy 16:13 ) 
 that the children of Israel should dwell in booths, in the feast of the
 seventh month:
 which was the same month, and this the second day of it, and therefore the time drew near for keeping it; for it was to begin the fifteenth.
