That is a pointed verse of Holy Scripture, instructing God’s ancient people in a particular way of life. The Jerusalem Council did not refer to this practice as the Gospel and Holy Spirit went forth among the Gentiles.
Personally I question the practice, as it seems geared toward making an impression on people so as to be awarded status. That is called “pride,” which in turn ought to be avoided.
