'Certainly' in the Bible

Then Saul said to Jonathan, Tell me what thou hast done. And Jonathan told him, and said, I did certainly taste a little honey with the end of the rod that was in my hand; and, lo, I must die.

Forgive, I pray thee, the trespass of thy handmaid: for Jehovah will certainly make my lord a sure house, because my lord fighteth the battles of Jehovah; and evil shall not be found in thee all thy days.
