Dayspring

Concise Bible Dictionary:

The word is from “to arise up” (Luke 1:7878Through the tender mercy of our God; whereby the dayspring from on high hath visited us, (Luke 1:78)). It is elsewhere translated “east” because it is in the east that the sun rises. Christ is here compared to the spring of day from on high, as the true heavenly light, “to give light to them that sit in darkness and in the shadow of death, to guide our feet into the way of peace.”
