“When the parents had gone out and shut the door of the room, as the two were alone, Tobias got out of bed and said to Sarah.
‘Sister, get up!
Let us pray and implore our Lord
That he may grant us mercy and safety.’
So she got up. They began to pray and implore that they might be kept safe.”
Now that Tobias had sent the demon fleeing because of the fish smell, Tobias and Sarah were alone in the bedroom. Tobias told Sarah, his new wife, to get up and pray so that they might be safe. He wanted God’s mercy. She did and they began to pray. You can see why many preachers would use this passage as an example for newlyweds.
