Deuteronomy 10:16

Circumcise therefore the foreskin of your heart, and be no more stiffnecked.

Deuteronomy 10:16 (KJV)

Context

Deuteronomy is the fifth book of the Old Testament and part of the Torah, the first five books traditionally ascribed to Moses. Here Moses speaks to Israel as they prepare to enter the Promised Land, recounting their wilderness journey and the laws God gave them. This verse is part of his call for wholehearted devotion to the Lord.

Meaning

Physical circumcision was the sign of God’s covenant with Abraham and his descendants (Genesis 17:10-14). Moses takes this familiar sign and applies it to the heart, which in biblical language means the core of a person’s being, including thoughts, desires, and motives. To “circumcise the foreskin of your heart” is to remove the hardness and stubbornness that block full submission to God. It is a call to repentance and inner transformation, not mere outward ritual. The image also points to removing what displeases God, such as carnality, sensuality, hypocrisy, and “superfluity of naughtiness,” and having what pleases Him put in their place.

The second command, “be no more stiffnecked,” uses the picture of a stubborn animal that resists its master’s yoke. Israel had often resisted God’s guidance during their wilderness wanderings. Moses urges them to abandon that rebellious attitude and instead humble themselves before the Lord.

Biblical connections

The New Testament echoes this teaching. In Romans 2:28-29, Paul explains that true circumcision is not outward in the flesh but inward, of the heart, by the Spirit. This shows that God has always desired inward transformation, not just external compliance. The same truth appears in Deuteronomy 30:6, where Moses promises that the Lord will circumcise the hearts of His people so they may love Him fully. This work is ultimately God’s, who alone can perform it and has promised to do so.

Application

This verse calls believers today to examine their own hearts. It invites us to identify areas of pride, self-will, and resistance to God’s will. Just as physical circumcision involved cutting away flesh, spiritual circumcision means cutting away whatever displeases God, such as hypocrisy, selfish desires, and disobedience. This is not something we can accomplish by our own effort alone; it is ultimately the work of God, who has promised to transform His people.

True obedience flows from a changed inner life. When the heart is right with God, outward actions follow naturally. Therefore, we should ask God to reveal any hardness in us and to give us a new, soft heart that delights in His commands.

Reflection

Consider your own walk with God. Are there areas where you have been stiffnecked, resisting His direction? The call to circumcise the heart is an invitation to surrender fully to Him. It is a daily choice to lay down pride and self-will, allowing God to shape our innermost being. As we respond in humility and obedience, we experience the freedom and joy of a heart fully devoted to Him.
