New Defender's Study Bible Notes
11:9 not hurt nor destroy. Even carnivorous animals can, if necessary, survive on herbivorous diets, as they were originally created to do. In the age to come, environmental conditions and plant nutrients will be so changed as to implement this practice once again, and there will be no more bloodshed, in nature, even among the animals.
11:10 root of Jesse. See note on Isaiah 11:1.
