Job 31:30

²⁸ This also were an iniquity to be punished by the judge: for I should have denied the God that is above.

²⁹ If I rejoiced at the destruction of him that hated me, or lifted up myself when evil found him:

Neither have I suffered my mouth to sin by wishing a curse to his soul.

³¹ If the men of my tabernacle said not, Oh that we had of his flesh! we cannot be satisfied.

³² The stranger did not lodge in the street: but I opened my doors to the traveller.

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