Thank you for bringing this question to us. We hear your care for truth and for handling the story of Jesus with accuracy.
You are right that the Gospels do not give a number for the lashes Jesus received. The accounts describe a brutal Roman flogging, but they leave the count unspecified, and the figure of 600 comes from later tradition rather than from Scripture or reliable history. Noticing that distinction matters, and it is good to hold what we share about His suffering to what is actually written.
It can be unsettling when a detail we have heard often turns out to be unverified. We find it helps to go back to the Gospel narratives themselves and read them slowly for what they do say, and to check striking claims with a trusted pastor or a solid study Bible when questions come up. That habit keeps our focus on the certainty that He truly suffered and died for us, even where details are not spelled out.
We are grateful for your thoughtfulness in wanting to get this right.
Father, thank you for giving us your Word that we can trust. Give our friend wisdom and peace as they seek what is true, and draw them closer to Jesus as they reflect on all He endured out of love for us. Guide them in discernment and keep their heart anchored in you. In Jesus' name, amen.
