'Briefly' in the Bible
[And] that the mystery (secret) was made known to me and I was allowed to comprehend it by direct revelation, as I already briefly wrote you.
I call on you, brethren, to listen patiently and bear with this message of exhortation and admonition and encouragement, for I have written to you briefly.
By Silvanus, a true (loyal, consistent, incorruptible) brother, as I consider him, I have written briefly to you, to counsel and urge and stimulate [you] and to declare [to you] that this is the true [account of the] grace (the undeserved favor) of God. Be steadfast and persevere in it.
I have written briefly to the church; but Diotrephes, who likes to take the lead among them and put himself first, does not acknowledge my authority and refuses to accept my suggestions or to listen to me.
