'Certainly' in the Bible

even as I swore to thee by Jehovah the God of Israel, saying, Solomon thy son shall reign after me, and he shall sit on my throne in my stead; even so will I certainly do this day.

of the nations of which Jehovah had said to the children of Israel, Ye shall not go in to them, neither shall they come in to you; they would certainly turn away your heart after their gods: to these Solomon was attached in love.

And Jehovah said to Solomon, Forasmuch as this is done by thee, and thou hast not kept my covenant and my statutes which I commanded thee, I will certainly rend the kingdom from thee, and will give it to thy servant:

For the word that he cried by the word of Jehovah against the altar in Bethel, and against all the houses of the high places that are in the cities of Samaria, shall certainly come to pass.

And Elijah said, As Jehovah of hosts liveth, before whom I stand, I will certainly shew myself to him to-day.
