### Biblical Occurrences & Contextual Analysis
The sole use of `{{G1603}}` is found in Acts, where it describes the culmination of a divine promise.

This fulfillment is directly linked to a prophecy written in the second psalm `{{G5568}}`: "Thou `{{G4771}}` art `{{G1488}}` my `{{G3450}}` Son `{{G5207}}`, this day `{{G4594}}` have I `{{G1473}}` begotten `{{G1080}}` thee `{{G4571}}`" [[Acts 13:33]]. The word underscores that the resurrection of Jesus is the definitive accomplishment of this scripture.
