This is interesting (supportive of corporate election in Scripture):
God chose the people of Israel in Abraham, Isaac, and Jacob/Israel (Deut 4:37; 7:6-8).9 That is, by choosing Jacob/Israel, the corporate/covenant representative, God also chose his descendants as his covenant people. It is a matter of Old Testament covenant theology. The covenant representative on the one hand and the people/nation of Israel on the other hand are the focus of the divine covenantal election, and individuals are elect only as members of the elect people. Moreover, in principle, foreign individuals who were not originally members of the elect people could join the chosen people and become part of the elect, demonstrating again that the locus of election was the covenant community and that individuals found their election through membership in the elect people.
