Genesis 17:19
Sarah <08283> [Sarah.]
Isaac <03327> [Isaac.]
{Yitzchak,} which we change into Isaac, signifies laughter; in allusion to Abraham's laughing, ver. 17. By this Abraham did not express his unbelief or weakness of faith, but his joy at the prospect of the fulfilment of so glorious a promise; and to this our Lord evidently alludes, Joh 8:56.
Genesis 21:12
<08085> [hearken.]
Isaac <03327> [in Isaac.]
Romans 9:7
<3754> [because.]
through Isaac <1722 2464> [In Isaac.]
