Matthew Poole and continuators on Deuteronomy 33:29

29 Happy art thou, O Israel; who is like unto thee, O people, saved by the LORD, the shield of thy help, and who is the sword of thy excellency! and thine enemies shall be found liars unto thee , and thou shalt tread upon their high places .

(i. e.) Shall be deceived as to all their vain hopes and confidences of destroying thee or saving themselves, whether grounded upon their own numbers and valour and strong holds, or upon old Prophesies and predictions of success, or upon their Idols. Or, shall lie unto thee, i. e. shall submit themselves to thee, though it be done but feignedly and by constraint, as this phrase is used Psal. 18. 44. & 66. 3. & 81. 15. Possibly this may design the lies and frauds which the Gibeonites would use to deceive them, Ios. 9. 4.

i. e. Thou shalt subdue their greatest princes, and their strongest holds, Deut. 32. 13. and their idols Temples and Worship.

z The giver and preserver of all that excellency, that glory, safety and happiness, which thou hast above all other people, which thou doest not obtain either by or for thy own wisdom or strength or goodness. Or, Thy most excellent sword, i. e. Thy strength and the authour of all thy past or approaching victories.

Marginal references: Or, shall be subdued.
