Now the priest of Midian had seven daughters, and they came and drew water and filled the troughs to water their father's flock.
Exodus 2:16

The number of Jethro's daughters is significant: seven lamps on the Menorah, seven penitent women in Isaiah 4:1, seven spirits of God in Revelation 3, seven congregations of Revelation 1-2, etc... #shmot
