{Until the death of Herod} (he(9373) t(8873) teleut(8873) H(8872)(9369)dou).
The Magi had been warned in a dream not to report to Herod and
now Joseph was warned in a dream to take Mary and the child along
(mellei z(8874)ein tou apolesai gives a vivid picture of the
purpose of Herod in these three verbs). In Egypt Joseph was to
keep Mary and Jesus till the death of Herod the monster. Matthew
quotes  Ho 11:1  to show that this was in fulfilment of God's
purpose to call his Son out of Egypt. He may have quoted again
from a collection of _testimonia_ rather than from the
Septuagint. There is a Jewish tradition in the Talmud that Jesus
"brought with him magic arts out of Egypt in an incision on his
body" (_Shabb_. 104b). "This attempt to ascribe the Lord's
miracles to Satanic agency seems to be independent of Matthew,
and may have been known to him, so that one object of his account
may have been to combat it" (McNeile).
