Isaiah 26:3 is a verse from the Book of Isaiah in the Hebrew Bible, which is part of the Christian Old Testament. The verse reads, "You will keep in perfect peace those whose minds are steadfast, because they trust in you" (NIV). In Hebrew, this verse is written as "תַּשִּׂים לַּה' מִשְׁמֶרֶת יִשָּׂא; כִּי בֵיטַחְתָּ בַּה' עוֹלָם מִשְׁמֶרֶת, כִּי בֵיטַחְתָּ בַּה' עוֹלָם מִשְׁמֶרֶת" (Isaiah 26:3). The verse is often interpreted as a promise of divine protection and peace for those who trust in God. The phrase "perfect peace" is translated in Latin as "pax perfecta" and in Greek as "εἰρήνην ἀκέραιον" (eirēnēn akéraion). Contextually, this verse is part of a song of trust in God's justice and deliverance, which is a central theme in the Book of Isaiah. The verse emphasizes the importance of faith and trust in God as a means to attain inner peace and security.
