The answer is: A kid and some unleavened cakes

Judges 6:19

When Gideon encountered the angel of the Lord, his offering of a kid goat and unleavened cakes was not merely a casual gesture but a significant act of faith and hospitality. In the ancient Near East, offering food to a visitor, especially a divine figure, invited blessings and showed respect. A kid goat symbolizes a younger animal, a choice offering which reflects the idea of giving one's best to God or a heavenly messenger.

Unleavened bread adds deeper layers to the symbolism. When the Israelites were liberated from Egypt, they had to bake bread quickly without yeast since they had to flee. This unleavened bread reminds us of the urgency and purity involved in their deliverance—intended as a holy place free of ritualistic additives.

Interestingly, the name Gideon translates to "destroyer," foreshadowing his role in the divinely appointed task of delivering Israel from the Midianites. This angelic encounter happens during a time of Israel’s infidelity, leading them into oppression, showing the cultural dynamic of wanting divine support amid struggles and dilemmas.

Trivia note: Gideon's story echoes through various narratives in the Bible. People often talk about his famed three hundred warriors, using a reduced troop size to emphasize reliance on God’s power rather than military might—again showcasing that stronger doesn’t always mean more, a lesson still prevalent in many teachings today! Gideon’s story is just one chef's bite into the rich feast of lessons in Judges.
