Psalms 44:2,3

How thou didst drive out the heathen, &c. The seven nations of the Canaanites out of Canaan, and settled in their stead thy people Israel, whom thou didst transplant thither from Egypt. Didst afflict the people The heathen; and cast them out. They got not the land, &c., by their own sword That is, by their arms or valour. But thy right hand, &c ., and the light of thy countenance Thy favour, as the next words explain it; thy gracious and glorious presence, which went along with them. The many complete victories which Israel obtained over the Canaanites, under the command of Joshua, were not to be attributed to themselves; nor could they claim the glory of them. They were neither owing to their own merit nor their own light, but to God's favour and power engaged for them; without which all their own efforts and endeavours would have been fruitless.
