Josephus on Converts

It is also worthwhile to observe how our Lawgiver had regard for equity in relation to foreigners; for he will be shown to have made the best possible provision that we neither corrupt our own [traditions] nor bear ill-will toward those who prefer to partake in our ways. For as many who wish to come and live under the same laws as us, he extends a warm welcome, believing that familial connections are based not only on race but also on one’s course of life. Yet he was unwilling for those joining us casually to be admitted into communion with us.
