'A seed' signifies the ultimate and primary levels in a person. It also signifies good and truth from the Lord. In an opposite sense, it signifies falsity of doctrine and hellish falsity. 'A seed' signifies everyone who constitutes the Lord's spiritual kingdom and faith grounded in charity.

In Genesis 12:7, 8:15, 16, 'a seed' signifies love and everyone who has love.

It seems rather circular to say that “good” in the Bible represents good, but in a general sense it's true! The case is this: The Lord is love itself given form and expression as wisdom itself, and that Divine Love and Divine Wisdom flow down into us, into the world and into the Bible in an unending stream with endless variety. Divine Love gives rise to our loves, our affections, our desires for good and the joy we can feel; Divine Wisdom gives rise to facts, knowledge, intelligence, understanding and human wisdom. And the more we can bring those two aspects of our lives into harmony, the more elevated we can become -- which will in turn make us happier, more useful, and ultimately more angelic.
