Parallel
Matthew 1:18
Clementine Vulgate · Berean Standard Bible
Christi autem generatio sic erat : cum esset desponsata mater ejus Maria Joseph, antequam convenirent inventa est in utero habens de Spiritu Sancto.
This is how the birth of Jesus Christ came about: His mother Mary was pledged in marriage to Joseph, but before they came together, she was found to be with child through the Holy Spirit.
