   The adverbial form locates events and conditions in daylight: in Exodus 13:21 the APB renders the LORD's leading by a cloud “by day,” contrasted with fire by night; in Ezekiel 12:3 it renders the carrying out of captivity articles “by day before their eyes.” The same daylight setting appears with the cloud over the people in Numbers 10:34, shade from drought in Isaiah 4:6, and the sun's light in Jeremiah 31:35.

In the Anselm Project Bible: The APB commonly presents the term with “by day,” while some clauses use “daytime” or place it in a “day and night” contrast. These renderings confirm the verse-level temporal setting rather than fixing a separate English equivalent in every occurrence.
