Letter of Aristeas (eng)
7
7 For since you have a love of learning things that can benefit the mind, (and since) it is very much necessary to share (this knowledge) with all those who are like–minded, it is much more (necessary to share it) with you, who have a genuine disposition not only with respect to kinship, being a brother, but also (all the more) by (your) impulse toward the good, which is particular to ourselves.
