The verse isn't referring to eternal origins of the Messiah but the ancient Davidic origins of the Messiah, David's hometown Bethlehem. Sorry but there is no Behthlehem in eternity past. "Shepherd Your people with Your scepter, the flock of Your possession which dwells by itself in the woodland, in the midst of a fruitful field. Let them feed in Bashan and Gilead as in THE DAYS OF OLD." Micah 7:14. The exact same Hebrew language is used here by the same prophet just two chapters later. It does not, and cannot, mean "days of eternity" here and make any sense.

The passage is referring to the Messiah's ancient ancestral origins in Bethlehem, the home of Jesse and David. It is referring to the ancient days of Jesse and David and not to "eternity" past as Trinitarians have misconstrued it.
