Romani 9:10 Meaning and Commentary

Romans 9:10

And not only this
This instance of Ishmael and Isaac, is not the only one, proving that Abraham's natural seed, the children of the flesh, are not all children, the children of God:

but when Rebecca also had conceived by one, even by our father Isaac,
"it was said unto her", ( Romans 9:12 ) , being in a parenthesis, "the elder shall serve the younger".

10 Non solo; ma anche a Rebecca avvenne la medesima cosa quand’ebbe concepito da uno stesso uomo, vale a dire Isacco nostro padre, due gemelli;

11 poiché, prima che fossero nati e che avessero fatto alcun che di bene o di male, affinché rimanesse fermo il proponimento dell’elezione di Dio, che dipende non dalle opere ma dalla volontà di colui che chiama,

12 le fu detto: Il maggiore servirà al minore;
