Isaiah 55 & 56 – Covenants, Fasting, & Sabbaths

Very Interesting! The JSB reads Is. 55:3 as a transformation of the Davidic covenant given in 2 Sam 7, conferring royal status onto the entire nation of Israel rather than just a single anointed one or messiah. This, accordingly, reframes the original message so that God’s Word does not fail on account of fall of the kingly line of David, but is in fact fulfilled in the nation itself which lives on to this day.


Is. 55:6 through 56:8 apparently form the basis for some modern Jewish fast-day rituals. JSB notes that all current fast days relate in some way to the fall of Jerusalem and/or the exile. The Sabbath figures greatly in this passage. JSB describes the significance of Sabbath as “a palace in time” for the community now that the physical temple has been destroyed and is no longer available: “The Sabbath provides and opportunity for the Jewish community to come together in sacred time even when they no longer possess their sacred space.”

This concept helps explain the great importance placed on the Sabbath by Jews in a period without a physical temple. Isaiah expounds on this in his inclusion of foreigners and eunuchs: They shall receive all the riches of God so long as they observe several of God’s commandments, but the only specific law mentioned here, besides loving God, is to keep the Sabbath.

So what does the Sabbath mean in your life? What does it mean in light of the Work of Christ?
