If you see the donkey of someone who hates you fallen down under its load, do not leave it there; be sure you help your enemy with it.
NIV
If you see the donkey of one who hates you lying [helpless] under his load, you shall refrain from leaving the man to cope with it alone; you shall help him to release the animal.
AMP
If thou see the ass of him that hateth thee lying under his burden, and wouldest forbear to help him, thou shalt surely help with him.
KJV
