Isaiah 40:31 is a verse from the Book of Isaiah in the Hebrew Bible, which is part of the Christian Old Testament. The verse reads: "But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint." In Hebrew, this verse is written as: "אַךְ-בֹּחֲלִים בַּה' יְחַדְּלוּ כֹחַ, יִנָּשְׂאוּ בְּכַנְפֵי-נֶשֶׁר; יָרֻצוּ וְלֹא יִיגָעוּ, יְהַלְּכוּ וְלֹא יִעָפוּ". The verse is often interpreted as a promise of divine strength and endurance for those who trust in God. It is part of a larger section (Isaiah 40:1-11) that offers comfort and hope to the people of Israel during their exile in Babylon, assuring them of God's care and the coming of a new era. The imagery of eagles, which are known for their strength and high flight, symbolizes the elevated spiritual state and renewed vitality that believers will experience. This verse has been widely translated and is found in many languages, including Spanish: "Mas los que esperan a Jehová tendrán nuevas fuerzas; levantarán alas como águilas; correrán, y no se cansarán; caminarán, y no se fatigarán", and German: "Aber die auf den HERRN harren, kriegen neue Kraft, dass sie aufwärts schießen wie Adler; sie laufen und werden nicht matt, sie gehen und werden nicht müde".
