本文探究路德對申命記四章7節中形容神的全稱名字的複數形式形容詞所作的三一性解釋的歷史與解經脈絡。假設申命記四章7節只是使用上帝的幾個複數形式之一，並且路德由此得出希伯來聖經中三一概念出現的證據，本文將檢視該段經文在他的三一論證中的功能。為展示路德為支持早期教父的三一論和基督論教義的典型特徵，本文將列舉他關於馬索拉拼音的可靠性的論述，並且將討論他對猶太宗教和猶太人的觀點。

The present paper explores the historical and exegetical context of Luther’s trinitarian exposition of the plural form of the adjective qualifying the generic name of God in Deuteronomy 4:7. Granted that Deuteronomy 4:7 utilises only one of several plural forms applied to the Divine and adduced by Luther as proof of the presence of the trinitarian concept within the Hebrew Bible, the function of that biblical passage in his trinitarian argumentation from the Tanakh was examined. To display typical features of Luther’s use of Hebrew scholarship in favour of the Patristic trinitarian and christological doctrines, his statements about the reliability of the Masoretic vocalisation were outlined and his views on the Jewish religion and on the Jewish people were discussed.
