Exodus 18:7

And Moses went out to meet his father in law, and did obeisance, and kissed him; and they asked each other of their welfare; and they came into the tent.

Moses went out ... Their salutations would be marked by all the warm and social greeting of Oriental friends (see the note at Exodus 4:27) - the one going out to "meet" the other-the "obeisance," the "kiss" on each side of the head, the silent entrance into the tent for consultation; and their conversation ran in the strain that might have been expected of two pious men, rehearsing and listening to a narrative of the wonderful works and providence of God.
