1 Samuel 9:25

Samuel communed with Saul Concerning the kingdom designed for him by God, and his administration of the government; upon the top of the house For coolness in the evening, and privacy. The Vulgate adds here, Saul prepared him a bed on the top of the house, and slept, an addition which Houbigant approves, accounting very plausibly for the deficiency of the Hebrew. The Seventy also understood the passage in a similar way, translating it, And they spread a bed for Saul on the top of the house, and he slept.
