Read It With
- Isaiah 51:9–16
Read Isaiah 51:9 with 51:9–16. By itself, “Awake, awake, put on strength, O arm of the LORD” can be detached from the speaker, addressee, historical horizon, poetic movement, or outcome that gives it force. The complete unit establishes: A plea recalls Rahab, the sea, and exodus; returning joy is promised, mortal fear is challenged, and the planted word identifies Zion as the LORD's people.
