God foretold free acts centuries ahead: the oppression in Egypt (Genesis 15)
Countless examples from Scripture prove that God foretold many things that human beings would freely do many ages later.
In Genesis 15 God foretold that the Egyptians would oppress Abraham's descendants for four hundred years, and that in oppressing that people they would sin gravely and bring God's wrath on themselves. 'Know for certain,' God says to Abraham, 'that your descendants will be strangers in a land that is not theirs; they will be enslaved and oppressed for four hundred years. But I will judge the nation they serve.'
Latin
III. Porro Deum multa praedixisse pluribus post seculis ab hominibus libere agenda, innumeris exemplis ex Scriptura probari potest. Sic decimo quinto capite Geneseos, Praedixit Deus Aegyptios afflicturos semen Abrahami quadringentis annis, & eos, populum illum sic affligendo, graviter peccaturos esse, & iram Dei in se provocaturos. Scito, inquit Deus Abrahamo, quod peregrinum futurum sit semen tuum in terra non sua: & subjicient eos servituti, & affligent quadringentis annis. Veruntamen gentem cui servituri sunt ego judicabo.
