In 1 Samuel 3:12, God confirms He will carry out the same judgment against Eli's house, reinforcing the sign of the sons' deaths.

1 Samuel 4:11 records the exact fulfillment: Hophni and Phinehas are slain in one day, as the sign predicted.

1 Samuel 4:17 reports the same fulfillment from the messenger, confirming the deaths of Eli's two sons.

1 Samuel 1:3 introduces Hophni and Phinehas, the sons whose deaths are the sign — narrative background.

Psalm 78:64 recounts the same event: the priests (Eli's sons) fell by the sword, confirming the sign given here.
