'One by one' in the Bible

Tomorrow morning you are to come forward tribe by tribe. The tribe that the LORD selects is to come forward by tribes, the tribe that the LORD selects is to come forward by households, and the household that the LORD selects is to come forward one by one.

Next, he brought near his household one by one, and Carmi's son Achan, grandson of Zabdi and great-grandson of Zerah, was selected from the tribe of Judah.
