'Last Day' in the Bible

Also day by day, from the first day to the last day, he read in the book of the law of God. They kept the feast seven days; and on the eighth day was a solemn assembly, according to the ordinance.

Afterward the children of Israel shall return, and seek the LORD their God, and David their king, and shall come with trembling to the LORD and to his blessings in the last days.
