John Gill Commentary Zechariah 12:14

"all the families that remain, every family apart, and their wives apart." — Zechariah 12:14 (ASV)

All the families that remain
That will be in being in those times;

every family apart, and their wives apart ;
for the whole nation shall be born at once, and converted, and all Israel shall be saved, (Isaiah 66:8) (Romans 11:26) .
