Anthropological: In the proposed context, these words take on an increasingly poignant aspect. Directing himself to the "pure in heart", those women who face a life in a foreign village as plural wives in a foreign culture, he tells them to turn to God and to feast upon his love. Note the next phrase: "...for ye may, if your minds are firm, forever."
Let us look upon the situation as it might have been. Jacob is addressing a mixed crowd, among whom are both the men who have become wealthy traders, and the women whom they have "traded" away (probably more for the creation of alliances than as merchandise, but the effect is the same for the women). These women will be sent "away into captivity" where they will be in a new culture with not only different marriage rules, but a different religion. As believers who are being sent away from their community of belief Jacob enjoins them to pray, and to feel the love of God. His last comment is the most poignant, for he tells them that if they remain steadfast, they may feel that love forever - even though they are away from that community of belief!
