ACT 20:28

28 Pay attention to yourselves and to all the Eder Hashem[(flock of G-d)] in which the Ruach Hakodesh has placed you as mashgichim ruchaniyim [(spiritual overseers)] to do the work of ro'im [(shepherds)] over the Kehillah of Hashem which Adoneinu purchased for the Geulah with his own dahm.
