Psalm 119:138 says that God gives his commands in righteousness, meaning they are rightly and justly made, and that they can be fully relied upon. The verse is a confession of faith: the psalmist is affirming that God’s instructions are good and dependable. It is spoken by the psalmist, the unnamed writer of Psalm 119, who addresses God directly in the middle of a long prayer about loving and living by God’s word.
You have commanded your statutes in righteousness. They are fully trustworthy.

What Psalm 119:138 Means
The phrase “You have commanded your statutes” points to God as the author of the law. The word “statutes” refers to the decrees and directions God has given his people, the settled guidance that shapes how a person should live. The psalmist is not describing these commands as a burden imposed from outside but as something God has actually spoken and set in place.
The next phrase, “in righteousness,” says something about the character behind those commands. Righteousness means that God’s will is just, upright and consistent with who he is. The commands do not come from whim or favoritism. They reflect a holy God who always does what is right.
The final words, “They are fully trustworthy,” are the heart of the verse. The psalmist is saying that God’s commands can be leaned on completely. The verse does not promise that obeying them will make life easy or free from pain, and it does not guarantee any particular outcome in a given situation. It makes a claim about the reliability of God’s word itself.
The Context of Psalm 119:138
Psalm 119 is the longest chapter in the Psalms, and it is an acrostic poem with twenty-two sections, each based on a letter of the Hebrew alphabet. Its theme is the law of God, which the psalm praises using a range of words including statutes, precepts, commands and promises. The writer is traditionally thought to be King David, though the psalm itself does not name its author, and many scholars regard it as a later composition in the wisdom tradition.
The verses just before and after Psalm 119:138 shape how it reads. In verse 135 the psalmist asks God to teach him his statutes, and in verse 136 he weeps because others refuse to keep God’s law. Verse 139 says his zeal wears him out because his enemies ignore God’s words, and verse 140 declares that God’s promises have been thoroughly tested. Read in this setting, the statement that God’s commands are trustworthy is a conviction held under pressure, from someone who is grieved by disobedience around him and sustained by confidence in God’s faithfulness.
