'Fervently' in the Bible

I will fervently thank the Lord with my mouth;I will praise Him in the presence of many.

Their Redeemer is strong;Yahweh of Hosts is His name.He will fervently plead their caseso that He might bring rest to the earthbut turmoil to those who live in Babylon.

When their drinking is over,they turn to promiscuity.Israel’s leaders fervently love disgrace.
