Psalms 10:7

His mouth is full of cursing and deceit and fraud: under his tongue is mischief and vanity.

Psalms 10:7 (KJV)

Context

Psalm 10 is a lament. The psalmist cries out because wicked people seem to prosper while the righteous suffer. This verse gives a sharp picture of the wicked person’s character, especially the harm done through speech. The wicked boast and think God will not call them to account, but the psalmist knows God sees their deeds.

Meaning

The mouth is described as “full” of cursing, deceit, and fraud. The word “full” shows that harmful speech is not rare; it overflows from the person. Cursing means words that wish evil on others. Deceit is lying and misleading. Fraud is cheating and oppression, often using false words to take advantage of the weak. These are not just harsh words; they are active tools of harm.

“Under his tongue” means hidden, stored-up malice. The tongue may be quiet for a moment, but underneath are mischief and vanity. Mischief is trouble and harm. Vanity is emptiness and worthlessness. The wicked person’s words may sound smooth, but they hide evil plans. What is in the heart eventually comes out in speech. The Hebrew words also carry ideas of violence and sorrow, showing the full damage such speech causes.

Biblical connections

This verse connects with the wider teaching of Scripture that the mouth reveals the heart. Jesus teaches that out of the abundance of the heart the mouth speaks (Matthew 12:34). The same truth appears here: the wicked person’s speech exposes inner corruption. The psalmist later cries for God to arise and defend the helpless (Psalm 10:12), showing that God hears the cries of the oppressed and will judge the wicked. This verse is a warning that hidden malice will not stay hidden forever.

Application

We can examine our own words. Do we speak truth, or do we deceive? Do our words build others up, or do they tear down? This verse warns us not to let cursing, deceit, or vanity become habits. It also reminds us that hidden motives matter. Even if we do not speak evil aloud, the intentions stored under the tongue are known to God. We must ask Him to search our hearts and reveal any hidden wrong.

Reflection

The cure for evil speech is a changed heart. When God transforms the heart, the mouth begins to speak what is true and good. This verse calls us to ask God to purify our inner thoughts so that our words bring honour to Him and blessing to others. Let us pray for clean hearts, so that our speech reflects His righteousness.
