Deu 14:1-2 “You are the sons of the LORD your God. You shall not cut yourselves or make any baldness on your foreheads for the dead. For you are a people holy to the LORD your God, and the LORD has chosen you to be a people for his treasured possession, out of all the peoples who are on the face of the earth.
John 1:12 But to all who did receive him, who believed in his name, he gave the right to become children of God,

“The cutting of the body and the shaving of the head were common mourning rites in the ancient Near East and are referred to in many places in the Old Testament (Isaiah 3:24; 15:2; 22:12; Jeremiah 16:6; 41:5; Ezekiel 7:18; Amos 8:10; Micah 1:16).” (Thompson)
Among Christians today, there is something wrong if our burial customs are just as the rituals of the ungodly. Paul wrote in 1 Thessalonians 4:13: But I do not want you to be ignorant, brethren, concerning those who have fallen asleep, lest you sorrow as others who have no hope. We may certainly mourn the passing of our loved ones, but as those who have eternal hope in Jesus, we should be different in our mourning. (Guzik)
Ye are not only the creatures, and the offspring, but the peculiar people, the worshippers, the servants, and those of you that are truly pious, the adopted children of Jehovah, the one living and true God, who is your God in covenant; and therefore you should not dishonour him, your heavenly Father, nor disparage yourselves, by unworthy or unbecoming practices. (Benson)
God’s people are required to be holy, and if they are holy, they are indebted to the grace God which makes them so. Those whom God chooses to be his children, he will form to be a holy people, and zealous of good works.

Ye are the children of the Lord your God,…. Some of them were so by the special grace of adoption, and all of them by national adoption; which was the peculiar privilege of the people of Israel, and laid them under great obligation to honour and obey the Lord their God, who stood in the relation of a father to them, and they of children to him. (Gill)
The Israelites were not only to suffer no idolatry to rise up in their midst, but in all their walk of life to show themselves as a holy nation of the Lord. (Keil)
