Deuteronomy 25:7
And if the man does not wish to take his brother's wife, then his brother's wife shall go up to the gate to the elders and say, 'My husband's brother refuses to perpetuate his brother's name in Israel; he will not perform the duty of a husband's brother to me.'
Ruth 4:1-2
Now Boaz had gone up to the gate and sat down there. And behold, the redeemer, of whom Boaz had spoken, came by. So Boaz said, "Turn aside, friend; sit down here." And he turned aside and sat down.
Ruth 4:5-6
Then Boaz said, "The day you buy the field from the hand of Naomi, you also acquire Ruth the Moabite, the widow of the dead, in order to perpetuate the name of the dead in his inheritance."
