Charles Ellicott Commentary Judges 19:5

"And it came to pass on the fourth day, that they arose early in the morning, and he rose up to depart: and the damsel`s father said unto his son-in-law, Strengthen thy heart with a morsel of bread, and afterward ye shall go your way." — Judges 19:5 (ASV)

Early in the morning. —Except in winter, most journeys are performed in the early morning or late evening, in order to avoid the burning heat.

Comfort your heart. —Literally, Prop up your heart, as in Genesis 18:5. This resembles the Latin expression cor fulcire.
