Azay is a rare adverb meaning "then" or "at that time," appearing in early Hebrew poetry. It marks a temporal sequence — often pointing to a pivotal moment of action, response, or divine intervention. Related to the common adverb az (H227).
The adverb azay appears in the Song of Moses (Exodus 15), marking the moment of Israel's triumphant song after the Red Sea deliverance. "Then" marks the hinge of sacred history — the before and after of divine rescue. God's interventions in time transform "then" into testimony.
