Hello, the verse itself shows it is talking about the coming Messiah for he is from everlasting, eternity which can only be the Son of God.
"But thou, Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel;
whose goings forth have been from of old, from everlasting. [everlasting: Heb. the days of eternity] (Mic 5:2, KJV)
The bracketed above is the KJV Marginal Note for the the verse. Below is the English translation of the Septuagint which was used by Jesus and the Apostles.
"And thou, Bethleem, house of Ephratha, art few in number to be reckoned among the thousands of Juda; yet out of thee shall one come forth to me, to be a ruler of Israel; and
his goings forth were from the beginning, even from eternity." (Mic 5:2, LXXE)
The idea of a verse having more than one interpretation or meaning is contrary to sound principles of interpretation.
"It is an unscientific method of interpretation. 1. It assumes without evidence that the writers of the Bible were not revealers, but concealers, of truth; for many of the meanings are hidden rather than manifested by the authors. 2. It assumes that it were better for man that God should cover up much of the truth than that He should openly declare it. 3. It turns all Biblical interpretation into the realm of fancy and fiction; for, since only one meaning appears in the text, the fancy of the interpreter must
supply the others. 4. It affords no limit to the distortions which hermeneutical dreamers may produce in Biblical exegesis. 5. It fails utterly to develop any new truth, since the interpreters must bring to each passage from some other source all the spiritual meaning which they allege that it should bear.
These facts, that are apparent to every unprejudiced reader, lead us to the only natural and scientific ground, which we may express in the
RULE:—Any expression in any given connection should yield but one meaning. page 138, 139"
