Who said, "Wherever you go, I will go… your people will be my people, and your God will be my God"?

Answer: Ruth

Ruth refused to leave Naomi, vowing that only death would separate them.

“But Ruth replied: “Do not urge me to leave you or to turn from following you. For wherever you go, I will go, and wherever you live, I will live; your people will be my people, and your God will be my God.”— Ruth 1:16 (BSB)
