Bumaba si Samson kasama ang kanyang ama at ang kanyang ina sa Timna. Nang dumating sila sa mga ubasan ng Timna, biglang may isang batang leon na umaatungal na sumalubong sa kanya.
Rashbam
גור אריה יהודה, an expression similar to כפיר אריות, (Judges 14,5) the young, not fully grown lion is called גור, whereas the fully mature lion is known as כפיר as we know from Ezekiel 19,2 בתוך כפירים רבתה גוריה, “a young lioness crouched among the fully grown lions.” The young lion enjoys the advantage of speed and self-confidence, hence more aggressiveness, over an aging lion. It is not surprising therefore that when complimenting Yehudah, Yaakov compares him to a young lion rather than to a fully mature one who is already on the way to decline.
Radak
ויעל, here the trip to Timnatah is described as an ascent, whereas in Judges 14,5 Shimshon is described as descending to that town. It all depends on the location from which one sets out.
