Exodus 23:5

³ Neither shalt thou countenance a poor man in his cause.

⁴ If thou meet thine enemy’s ox or his ass going astray, thou shalt surely bring it back to him again.

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.

⁶ Thou shalt not wrest the judgment of thy poor in his cause.

⁷ Keep thee far from a false matter; and the innocent and righteous slay thou not: for I will not justify the wicked.

Do read the surrounding verses too, because the context often says more than a single verse.
