These are the 10 Commandments quoted from the King James Version (KJV) Bible, and take note of the yellow highlights:

Exodus 20:1-17 King James Version (KJV)
¹ And God spake all these words, saying,
² I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage.
³ Thou shalt have no other gods before me.
⁴ Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.
⁵ Thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;
⁶ And shewing mercy unto thousands of them that love me, and keep my commandments.
⁷ Thou shalt not take the name of the Lord thy God in vain; for the Lord will not hold him guiltless that taketh his name in vain.
⁸ Remember the sabbath day, to keep it holy.
⁹ Six days shalt thou labour, and do all thy work:
¹⁰ But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
¹¹ For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it.
¹² Honour thy father and thy mother: that thy days may be long upon the land which the Lord thy God giveth thee.
¹³ Thou shalt not kill.
¹⁴ Thou shalt not commit adultery.
¹⁵ Thou shalt not steal.
¹⁶ Thou shalt not bear false witness against thy neighbour.
¹⁷ Thou shalt not covet thy neighbour’s house, thou shalt not covet thy neighbour’s wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbour’s.

Below is the Catechism of the Roman Catholic Church, with the yellow highlights directly compared to the KJV Bible, while the empty yellow highlight confirms the 2nd Commandment in the Bible has been removed from the Catholic Catechism:

A Traditional Catechetical Formula
1. I am the LORD your God: you shall not have strange Gods before me.
2. You shall not take the name of the LORD your God in vain.
3. Remember to keep holy the LORD’S Day.
4. Honor your father and your mother.
5. You shall not kill.
6. You shall not commit adultery.
7. You shall not steal.
8. You shall not bear false witness against your neighbor.
9. You shall not covet your neighbor’s wife.
10. You shall not covet your neighbor’s goods.

In more detail, the Roman Catholic Church has modified the first commandment from this:

Exodus 20:3 King James Version (KJV)
³ Thou shalt have no other gods before me.

To this:

A Traditional Catechetical Formula
1. I am the LORD your God: you shall not have strange Gods before me.

The Catechism has completely removed the 2nd commandment from this:

Exodus 20:4 King James Version (KJV)
⁴ Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.

To this:

The Holy Bible quotes the 4th Commandment to be this:

Exodus 20:8-11 King James Version (KJV)
⁸ Remember the sabbath day, to keep it holy.
⁹ Six days shalt thou labour, and do all thy work:
¹⁰ But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
¹¹ For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it.

However, the Roman Catholic Catechism has changed the 4th Commandment to be their 3rd commandment, and to state this:

A Traditional Catechetical Formula
3. Remember to keep holy the LORD’S Day.

The “LORD’s Day” of the Roman Catholic Church is not the same as the Saturday Sabbath referred to in the Bible, but is referring to Sunday, or “day of the sun”, which is a pagan tradition of literal sun worship:

Catechism of the Catholic Church
The Lord’s day
1166 “By a tradition handed down from the apostles which took its origin from the very day of Christ’s Resurrection, the Church celebrates the Paschal mystery every seventh day, which day is appropriately called the Lord’s Day or Sunday.“³⁶ The day of Christ’s Resurrection is both the first day of the week, the memorial of the first day of creation, and the “eighth day,” on which Christ after his “rest” on the great sabbath inaugurates the “day that the Lord has made,” the “day that knows no evening.”³⁷ The Lord’s Supper is its center, for there the whole community of the faithful encounters the risen Lord who invites them to his banquet:³⁸
The Lord’s day, the day of Resurrection, the day of Christians, is our day. It is called the Lord’s day because on it the Lord rose victorious to the Father. If pagans call it the “day of the sun,” we willingly agree, for today the light of the world is raised, today is revealed the sun of justice with healing in his rays.³⁹

The 10th Commandment in the Bible is quoted as the following:

Exodus 20:17 King James Version (KJV)
¹⁷ Thou shalt not covet thy neighbour’s house, thou shalt not covet thy neighbour’s wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbour’s.

Since the Catholic Catechism completely removed the 2nd Commandment as found in the Holy Bible, they needed to split the 10th Commandment in the Bible into 2 separate commandments:

A Traditional Catechetical Formula
9. You shall not covet your neighbor’s wife.
10. You shall not covet your neighbor’s goods.
