'Heard' in the Bible

This is the Message which we have heard from the Lord Jesus and now deliver to you--God is Light, and in Him there is no darkness.

Dear children, the last hour has come; and as you once heard that there was to be an anti-Christ, so even now many anti-Christs have appeared. By this we may know that the last hour has come.

For this is the Message you have heard from the beginning--that we are to love one another.

and that no spirit is from God which does not acknowledge this about Jesus. Such is the spirit of the anti-Christ; of whose coming you have heard, and it is already in the world.
