Glossa Ordinaria

Morally; Abraham signifies to us the virtue of faith in Christ, as an example himself, as it is said of him, Abraham believed God, and it was accounted unto Him for righteousness. Isaac may represent hope; for Isaac is interpreted ‘laughter,’ as he was the joy of his parents; and hope is our joy, making ns to hope for eternal blessings and to joy in them. Abraham begat Isaac, and faith begets hope. Jacob signifies ‘love,’ for love embraces two lives; active in the love of our neighbour, contemplative in the love of God; the active is signified by Leah, the contemplative by Rachel. For Leah is interpreted. ‘labouringh,’ for she is active in labour; Racheli ‘having seen the beginning,’ because by the contemplative, the beginning, that is God, is seen. Jacob is born of two parents, as love is born of faith and hope; for what we believe, we both hope for and love.
