Jonah 1:16

1:16 The men feared the Lord greatly, and earnestly vowed to offer lavish sacrifices to the Lord.

Jonah 1:9-10

1:9 He said to them, “I am a Hebrew! And I worship the Lord, the God of heaven, who made the sea and the dry land.” 1:10 Hearing this, the men became even more afraid and said to him, “What have you done?” (The men said this because they knew that he was trying to escape from the Lord, because he had previously told them.)
