Albert Barnes Commentary Judges 14:10

"And his father went down unto the woman: and Samson made there a feast; for so used the young men to do." — Judges 14:10 (ASV)

Made a feast ... - This was the wedding-feast, protracted in this instance seven days, in that of Tobias fourteen days. It was an essential part of the marriage ceremony (Genesis 29:22; Esther 2:18; Matthew 22:2–4; Revelation 19:7, 9).
