'Message' in the Bible

For if the message given through angels [the Law given to Moses] was authentic and unalterable, and every violation and disobedient act received an appropriate penalty,

For indeed we have had the good news [of salvation] preached to us, just as the Israelites also [when the good news of the promised land came to them]; but the message they heard did not benefit them, because it was not united with faith [in God] by those who heard.

and to Jesus, the Mediator of a new covenant [uniting God and man], and to the sprinkled blood, which speaks [of mercy], a better and nobler and more gracious message than the blood of Abel [which cried out for vengeance].

I call on you, brothers and sisters, listen [patiently] to this message of exhortation and encouragement, for I have written to you briefly.
