Matthew Henry on Joshua 9:1-2

Hitherto the Canaanites had defended themselves, but here they consult to attack Israel. Their minds were blinded, and their hearts hardened to their destruction. Though often at enmity with each other, yet they united against Israel. Oh that Israel would learn of Canaanites, to sacrifice private interests to the public welfare, and to lay aside all quarrels among themselves, that they may unite against the enemies of God's kingdom! (Jos 9:3-13)
