| Geneva Study Bible Wherefore they that speak in proverbs say, Come into Heshbon, let the city of Sihon be built and prepared: Wesley's Notes 21:27 In proverbs - The poets or other ingenious persons, of the Amorites or Canaanites, who made this following song of triumph over the vanquished Moabites: which is here brought in, as a proof that this was now Sihon's land, and as an evidence of the just judgment of God in spoiling the spoilers, and subduing those who insulted over their conquered enemies. Come into Heshbon - These are the words either of Sihon speaking to his people, or of the people exhorting one another to come and possess the city which they had taken. Of Sihon - That which once was the royal city of the king of Moab, but now is the city of Sihon. Jamieson-Fausset-Brown Bible Commentary 27-30. Wherefore they that speak in proverbs-Here is given an extract from an Amorite song exultingly anticipating an extension of their conquests to Arnon. The quotation from the poem of the Amorite bard ends at Nu 21:28. The two following verses appear to be the strains in which the Israelites expose the impotence of the usurpers. Matthew Henry's Concise Commentary 21:21-35 Sihon went with his forces against Israel, out of his own borders, without provocation, and so ran upon his own ruin. The enemies of God's church often perish by the counsels they think most wisely taken. Og, king of Bashan, instead of being warned by the fate of his neighbours, to make peace with Israel, makes war with them, which proves in like manner his destruction. Wicked men do their utmost to secure themselves and their possessions against the judgments of God; but all in vain, when the day comes on which they must fall. God gave Israel success, while Moses was with them, that he might see the beginning of the glorious work, though he must not live to see it finished. This was, in comparison, but as the day of small things, yet it was an earnest of great things. We must prepare for fresh conflicts and enemies. We must make no peace or truce with the powers of darkness, nor even treat with them; nor should we expect any pause in our contest. But, trusting in God, and obeying his commands, we shall be more than conquerors over every enemy. |
