'Appointed' in the Bible

Yahweh said to him, "Therefore whoever slays Cain, vengeance will be taken on him sevenfold." Yahweh appointed a sign for Cain, lest any finding him should strike him.

Adam knew his wife again. She gave birth to a son, and named him Seth, "for God has appointed me another child instead of Abel, for Cain killed him."

Let it happen, that the young lady to whom I will say, 'Please let down your pitcher, that I may drink,' and she will say, 'Drink, and I will also give your camels a drink,' -- let her be the one you have appointed for your servant Isaac. By this I will know that you have shown kindness to my master."

and she will tell me, "Drink, and I will also draw for your camels," -- let her be the woman whom Yahweh has appointed for my master's son.'
