'Understood' in the Bible

let it be known and clearly understood by all of you, and by all the people of Israel, that in the name of Jesus Christ the Nazarene, whom you [demanded be] crucified [by the Romans and], whom God raised from the dead—in this name [that is, by the authority and power of Jesus] this man stands here before you in good health.

So let it be clearly known by you, brothers, that through Him forgiveness of sins is being proclaimed to you;

Therefore let it be known to you that [this message of] the salvation of God has been sent to the Gentiles; they indeed will listen!”
