John Gill Commentary Psalms 8:7

"All sheep and oxen, Yea, and the beasts of the field," — Psalms 8:7 (ASV)

All sheep and oxen
The tame creatures, which are useful for food and clothing:

yea, and the beasts of the field ;
the wild beasts, which he can make use of to destroy and devour his enemies, and whom he can restrain from harming his own people, (Jeremiah 15:8) (Daniel 6:22) (Acts 28:3–5) .
