וַיִּקְרָ֤א עֵלִי֙ אֶת־שְׁמוּאֵ֔ל וַיֹּ֖אמֶר שְׁמוּאֵ֣ל בְּנִ֑י וַיֹּ֖אמֶר הִנֵּֽנִי׃
Then Eli called Samuel, and said: ‘Samuel, my son.’ And he said: ‘Here am I.’
Ibn Ezra
השמן Make fat. According to some it is infinitive, like הקטר To burn incense (1 Sam. 3:16); and הׇשַׁע likewise, like הׇרַע To do evil (Lev. 5:4); but this cannot be so, because of the conjunction פן lest.16Since the part beginning with lest is the secondary sentence, the preceding must be the principal one; and השמן ,השע, the verbs of the principal sentence, cannot be Infinitives. They are all rather imperative forms. We know that the prophet cannot make the heart fat; he shall only declare their heart to be so; there are many instances like it.
