Ethics toward Enemies and Strangers

Job 31:29-32

If I have rejoiced at the destruction of him that hated me, Or lifted up myself when evil found him

(Yea, I have not suffered my mouth to sin By asking his life with a curse);

If the men of my tent have not said, Who can find one that hath not been filled with his meat?

(The sojourner hath not lodged in the street; But I have opened my doors to the traveller);
