Ethics toward Enemies and Strangers

Job 31:29-32

If I rejoice at the ruin of my hater, And stirred up myself when evil found him,

Yea, I have not suffered my mouth to sin, To ask with an oath his life.

If not--say ye, O men of my tent, `O that we had of his flesh, we are not satisfied.'

In the street doth not lodge a stranger, My doors to the traveller I open.
