'Declare' in the Bible

that life was revealed,and we have seen itand we testify and declare to youthe eternal life that was with the Fatherand was revealed to us—

That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.

This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.
