Hen in Fausset's Bible Dictionary
Matthew 23:37; Luke 13:34. As "the eagle stirring up her nest,
fluttering over her young, spreading abroad her wings, taking,
bearing them on her wings," represents the Old Testament
aspect of Jehovah in relation to Israel under the law
(Deuteronomy 32:11), so the "hen," Christ the lowly loving Son
of God gathering God's children under His overshadowing wing,
in the gospel (Rth 2:12; Psalm 17:8; Psalm 91:4). (See EAGLE.)
So Jehovah "passed over", or sprang forward to overshadow
Israel from the destroying angel (Exodus 12:13). (See
PASSOVER; EXODUS.)
