Why does Samuel draw attention to the fact that he is the one who anointed Saul as king over Israel?
Samuel wants to emphasize the importance of listening to the word of the Lord. The same Lord who anointed Saul as king, now gives him a command to carry out.1
1 Samuel dit à Saül: C'est moi que l'Eternel a envoyé pour t'oindre roi sur son peuple, sur Israël: écoute donc ce que dit l'Eternel.
