The Ninth Commandment: You are not to covet your neighbor’s house.
What is this? Answer:
We are to fear and love God, so that we do not try to trick our neighbors out of their inheritance or property or try to get it for ourselves by claiming to have a legal right to it and the like, but instead be of help and service to them in keeping what is theirs.

My thoughts
Words have the power to create and to destroy. Being people of the Word, a word that transforms our lives in the gospel, God does not want us using our words to tear people down, or destroy those he calls us to bring life too.

Luther
"Besides our own body, our spouse, and our temporal property, we have one more treasure that is indispensable to us, namely, our honor and good reputation. For it is important that we not live among people in public disgrace and dishonor. [256] Therefore God does not want our neighbors deprived of their reputation, honor, and character any more than of their money and possessions; he wants everyone to maintain self-respect before spouse, child, servant, and neighbor."

James 3:1-12
"If we put bits into the mouths of horses so that they obey us, we guide their whole bodies as well. 4 Look at the ships also: though they are so large and are driven by strong winds, they are guided by a very small rudder wherever the will of the pilot directs. 5 So also the tongue is a small member, yet it boasts of great things.
How great a forest is set ablaze by such a small fire! 6 And the tongue is a fire, a world of unrighteousness. The tongue is set among our members, staining the whole body, setting on fire the entire course of life, and set on fire by hell. 7 For every kind of beast and bird, of reptile and sea creature, can be tamed and has been tamed by mankind, 8 but no human being can tame the tongue. It is a restless evil, full of deadly poison. 9 With it we bless our Lord and Father, and with it we curse people who are made in the likeness of God. 10 From the same mouth come blessing and cursing. My brothers, these things ought not to be so. 11 Does a spring pour forth from the same opening both fresh and salt water? 12 Can a fig tree, my brothers, bear olives, or a grapevine produce figs? Neither can a salt pond yield fresh water."

The Tenth Commandment: You are not to covet your neighbor’s wife, male or female servant, cattle, or whatever is his.

What is this? Answer:
We are to fear and love God, so that we do not entice, force, or steal away from our neighbors their spouses, household workers, or livestock, but instead urge them to stay and fulfill their responsibilities to our neighbors.

What then does God say about all these commandments? Answer:
God says the following: “I, the LORD your God, am a jealous God. Against those who hate me I visit the sin of the fathers on the children up to the third and fourth generation. But I do good to those who love me and keep my commandments to the thousandth generation.”

What is this? Answer:
God threatens to punish all who break these commandments. Therefore we are to fear his wrath and not disobey these commandments. However, God promises grace and every good thing to all those who keep these commandments. Therefore we also are to love and trust him and gladly act according to his commands.
