'Fervently' in the Bible

“I love You [fervently and devotedly], O Lord, my strength.”

God, you are my God! I will fervently seek you. My soul thirsts for you; my flesh longs for you in a dry, weary, and parched land.

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

Zayin.Remember [always] the word and promise to Your servant,In which You have made me hope.
