Matthew Poole and continuators on Isaiah 11:14

14 But they shall flie upon the shoulders of the Philistins toward the West, they shall spoil them of the East together: they shall lay their hand upon Edom and Moab, and the children of Ammon shall obey them.

Either it is a Metaphor from Birds and Beasts of Prey, which commonly fasten upon the Shoulders of Cattel; or from Wrestlers, who endeavour to catch hold of their Adversaries Shoulders, that they may throw them down. Or, shoulder is put for a side, as Numb. 34. 11. Ios. 15. 8, 10. or, for a Part or Quarter of a Country, as Deut. 33. 12.

They shall subdue them. Which is to be understood of the Spiritual Victory which the Jewish Messiah shall obtain by his Apostles and Ministers over all Nations, in bringing them to the Obedience of his Gospel. For it is the manner of the Prophets to speak of the Spiritual things of the Gospel under such Corporeal Representations.

Marginal references: Heb. the children of the East.; Heb. Edom and Moab shall be the laying on of their hand.; Heb. the children of Ammon their obedience.
