'Whenever' in the Bible

"Son of man, I have appointed you a watchman for the house of Israel. Whenever you hear a word from my mouth, you must give them a warning from me.

I brought them to the land which I swore to give them, but whenever they saw any high hill or leafy tree, they offered their sacrifices there and presented the offerings that provoke me to anger. They offered their soothing aroma there and poured out their drink offerings.

"As for you, son of man, I have made you a watchman for the house of Israel. Whenever you hear a word from my mouth, you must warn them on my behalf.
