'Come in Peace' in the Bible

So Samuel did what Yahweh said. He came to Bethlehem, and the elders of the city came trembling to meet him. They said, "{Have you come in peace}?"

and say, 'Thus says the king: "Put this [fellow in] the house of imprisonment and feed him reduced rations of food and water until I come in peace." '"

And David went out {to meet them} and answered and said to them, "If you come in peace to me, to help me, {my heart will be joined with you}, but if [you come] to betray me to my adversaries, although [there is] no wrong on my hands, may the God of our fathers see and pass judgment."
