1 Samuel
King James Version (KJV)

“Wherefore now return, and go in peace, that thou displease not the lords of the Philistines.”
King James Version (KJV)
29:8 David said &c. - This was deep dissimulation and flattery, no way to be justified. None knows, how strong a temptation they are in to compliment and dissemble, which they are in who attend great men.
29:9 Angel of God - In whom nothing is blame - worthy. The Heathens acknowledged good spirits, which also they worshipped as an inferior sort of deities, who were messengers and ministers to the supreme God; Achish had learned the title of angels, from the Israelites his neighbours, and especially from David's conversation.
