And it shall come to pass in that day, that his burden shall be taken away from off thy shoulder, and his yoke from off thy neck, and the yoke shall be destroyed because of the anointing.
His burden shall be taken away from off thy shoulder - the Assyrians' oppression shall be taken away (Isaiah 9:4). Judah was still tributary to Assyria; Hezekiah had not yet revolted, as he did in the beginning of Sennacherib's reign.
Because of - literally, from the face of (mipnee) (Hosea 10:15).
The anointing - namely, the anointing, or consecration, that is upon the elect nation, its prophets, priests, kings, and its holy place (Psalms 105:15), the Antitype to all which is the anointed Messiah (Daniel 9:24, "to anoint the Most Holy;" Psalms 2:2; Psalms 45:7; Luke 4:18; Luke 4:21). So the spiritual Israel, believers, have their anointing from Him (2 Corinthians 1:21-22; 1 John 2:20; 1 John 2:27). Just as in Isaiah 9:4-6, the 'breaking of the yoke of' the enemies' 'burden and staff' is attributed to Messiah - "Thou hast broken the yoke of his burden, and the staff of his shoulder;" "For unto us a child is born," etc., so it is here. Isaiah and Hezekiah, God's anointed prophet and king respectively, were the type, as it was from regard to their prayers that God delivered Judah from Sennacherib, (Isaiah 37:4; Isaiah 37:14-21, etc.) But it is for the sake of Messiah ultimately that all deliverances are vouchsafed to God's people. Parallel to Isaiah 8:10, "Take counsel together, and it shall come to nought ... for God is with us." or 'because of Immanuel.' Maurer, not so well, translates, 'because of the fatness:' an image of the Assyrians' fierce and wanton pride, drawn from a well-fed bull tossing off the yoke (Deuteronomy 32:15). So Isaiah 10:16 above, and Isaiah 5:17, "fat ones."
