15:38 Fringes - These were certain threads or ends, standing out a little further than the rest of their garments, lest there for this use. In the borders - That is, in the four borders or quarters, as it is, Deut 22:12. Of their garments - Of their upper garments. This was practiced by the Pharisees in Christ's time, who are noted for making their borders larger than ordinary. A ribband - To make it more obvious to the sight, and consequently more serviceable to the use here mentioned. Of blue - Or, purple.
15:37-41 The people are ordered by the Lord to make fringes on the borders of their garments. The Jews were distinguished from their neighbours in their dress, as well as in their diet, and thus taught not to be conformed to the way of the heathen in other things. They proclaimed themselves Jews wherever they were, as not ashamed of God and his law. The fringes were not appointed for trimming and adorning their clothes, but to stir up their minds by way of remembrance, 2Pe 3:1. If they were tempted to sin, the fringe would warn them not to break God's commandments. We should use every means of refreshing our memories with the truths and precepts of God's word, to strengthen and quicken our obedience, and arm our minds against temptation. Be holy unto your God; cleansed from sin, and sincerely devoted to his service; and that great reason for all the commandments is again and again repeated, I am the Lord your God.
