1 Sam 20:31

20:31 neither you nor your kingdom shall be established. Despite Samuel’s words in 13:14, Saul still clings to hope for his dynasty (cf. 18:8 note). Contrast Jonathan’s ready acceptance of the Lord’s will (v. 13; 18:4; 23:17 and notes). It may be inferred from Saul’s words that Jonathan was his firstborn and thus in line for the throne.
