The Hebrews used the term father in a great variety of senses - as a literal father, a grandfather, an ancestor, a ruler, an instructor. The phrase may either mean the same as the Eternal Father, and the sense will be, that the Messiah will not, as must be the ease with an earthly king, however excellent, leave his people destitute after a short reign, but will rule over them and bless them forever (Hengstenberg); or it may be used in accordance with a custom usual in Hebrew and in Arabic, where he who possesses a thing is called the father of it.
Thus, the father of strength means strong; the father of knowledge, intelligent; the father of glory, glorious; the father of goodness, good; the father of peace, peaceful. According to this, the meaning of the phrase, the Father of eternity, is properly eternal. The application of the word here is derived from this usage. The term Father is not applied to the Messiah here with any reference to the distinction in the divine nature, for that word is uniformly, in the Scriptures, applied to the first, not to the second person of the Trinity. But it is used in reference to durations, as a Hebraism involving high poetic beauty. lie is not merely represented as everlasting, but he is introduced, by a strong figure, as even the Father of eternity. as if even everlasting duration owed itself to his paternity. There could not be a more emphatic declaration of strict and proper eternity. It may be added, that this attribute is often applied to the Messiah in the New Testament; Joh_8:58; Col_1:17; Rev_1:11, Rev_1:17-18; Heb_1:10-11; Joh_1:1-2.
