He done

“the behemoth is a plant-eater (Job 40:15) that lives near water (verses 21–23). It is at home even in a flooded, raging river (verse 23). The behemoth is very strong and muscular (verses 16, 18); in fact, “it ranks first among the works of God” (verse 19), and only its Creator can master it. The behemoth has a massive tail that “sways like a cedar” (verse 17). Hunting the behemoth is futile, because it cannot be captured (verse 24).”
