Galatians 4:30

Cast out (ekbale). Second aorist active imperative of ekballw. Quotation from Genesis 21:10 (Sarah to Abraham) and confirmed in Genesis 21:12 by God's command to Abraham. Paul gives allegorical warning thus to the persecuting Jews and Judaizers. Shall not inherit (ou mh klhronomhsei). Strong negative (ou mh and future indicative). "The law and the gospel cannot co-exist. The law must disappear before the gospel" (Lightfoot). See Genesis 3:18 Genesis 3:29 for the word "inherit."
