From H3634 (kalal, 'to complete/perfect'). Kallah denotes a woman who is betrothed or newly married β the 'complete one' who has entered or is entering the covenant of marriage. It is used both literally and as a profound theological metaphor.
Kallah is one of the most beautiful theological words in Scripture. The entire Song of Solomon celebrates the bride β called kallah six times, described with tender adoration. More profoundly, the prophets use the bride metaphor for Israel's relationship with YHWH. Isaiah 62 declares that God rejoices over His people as a bridegroom rejoices over his bride. Jeremiah mourns that Israel forgot her God 'as a bride adorneth herself with her jewels.' The New Testament consummates this imagery: the Church is the Bride of Christ, and Revelation 21:2 presents the New Jerusalem 'prepared as a bride adorned for her husband.' The covenant of grace is a marriage covenant.
