Find Comfort in the Bible

Where to find scriptural help, regarding zeal:

John 2:13-17
When it was almost time for the Jewish Passover, Jesus went up to Jerusalem. In the temple courts he found men selling cattle, sheep and doves, and others sitting at tables exchanging money. So he made a whip out of cords, and drove all from the temple area, both sheep and cattle; he scattered the coins of the money changers and overturned their tables. To those who sold doves he said, "Get these out of here! How dare you turn my Father's house into a market!" His disciples remembered that it is written: "Zeal for your house will consume me."

John 6:27
Do not work for food that spoils, but for food that endures to eternal life, which the Son of Man will give you. On him God the Father has placed his seal of approval."
