Judges 12:6

12:6 then they said to him, “Say ‘Shibboleth!’” If he said, “Sibboleth” (and could not pronounce the word correctly), they grabbed him and executed him right there at the fords of the Jordan. On that day forty-two thousand Ephraimites fell dead.

Judges 16:3

16:3 Samson spent half the night with the prostitute; then he got up in the middle of the night and left. He grabbed the doors of the city gate, as well as the two posts, and pulled them right off, bar and all. He put them on his shoulders and carried them up to the top of a hill east of Hebron.
