In Exodus 4:24-26, the threat against Moses illustrates the severe penalty for neglecting circumcision as stated here.

Ezekiel 44:7 directly echoes both 'uncircumcised' and 'broken my covenant' — condemning Israel for allowing the uncircumcised into the sanctuary.

Joshua 5 describes a whole generation that had neglected circumcision being circumcised before entering Canaan — directly enacting the covenant requirement threatened here.

Numbers 9:13 uses identical 'cut off from his people' language for neglecting Passover. Same penalty formula applied to covenant disobedience.

In Galatians 5:12, Paul wishes circumcision agitators would 'cut off' themselves — ironically weaponizing the covenant penalty language against them.

Leviticus 26:15 echoes 'break my covenant' — the same consequence for violating God's covenant obligations appears in Israel's covenant blessings and curses.

Numbers 19:20 says 'cut off from among the congregation' for failing purification — same consequence pattern for covenant purity violations.
