Final answer:
God promises to circumcise the hearts of the Israelites in Deuteronomy, indicating a spiritual transformation and renewed commitment to His commandments.
Step-by-step explanation:
In the chapter of Deuteronomy, during the time of eschatological (post-exilic) salvation, God promises to transform the hearts of His people. Specifically, a key passage that speaks to this promise is found in Deuteronomy 30:6 where it is stated that God will circumcise the hearts of the Israelites, so that they may love Him with all their heart and with all their soul, for their good. The phrase 'circumcise the hearts' symbolically represents a deep, inner spiritual transformation that implies a turning away from previous disobediences and a renewed commitment to God's commandments. This promised action is in contrast to the many verses in the Old Testament, such as those in Ezekiel and Isaiah, where God enacts judgment on the Israelites for their disobedience and idolatry.
