Study Bible

Hear this, O house of Jacob
The phrase "Hear this" is a call to attention, a divine imperative that demands the audience's focus. In Hebrew, the word "hear" is "שְׁמַע" (shema), which implies not just listening but also obeying. This echoes the Shema in Deuteronomy 6:4, a central declaration of faith in Judaism. The "house of Jacob" refers to the descendants of Jacob, also known as Israel. Historically, this encompasses the twelve tribes, emphasizing their shared ancestry and covenantal relationship with God. It is a reminder of their identity and the responsibilities that come with it.

who are called by the name of Israel
The phrase "called by the name of Israel" signifies a divine naming and purpose. "Israel" means "God prevails" or "he struggles with God," originating from Jacob's wrestling with the angel in Genesis 32:28. This name change from Jacob to Israel marks a transformation and a mission. It is a reminder of their unique relationship with God and their role as His chosen people. The calling by this name is both an honor and a call to live up to the covenantal promises and responsibilities.

and who have come from the waters of Judah
"Waters of Judah" is a poetic expression referring to the lineage and origin of the people. Judah, one of Jacob's sons, became the leading tribe, from which King David and ultimately Jesus Christ descended. The "waters" symbolize life, continuity, and the flow of history. This phrase underscores the importance of heritage and the fulfillment of God's promises through the line of Judah, pointing to the Messianic hope.

who swear by the name of the LORD
To "swear by the name of the LORD" is to make a solemn oath invoking God's name, indicating a serious commitment to truth and faithfulness. In Hebrew culture, oaths were binding and sacred, reflecting one's integrity and relationship with God. This phrase highlights the expectation that the people of Israel should live in a manner that honors God's name, adhering to His commandments and reflecting His character.

and invoke the God of Israel
"Invoke the God of Israel" suggests calling upon God in prayer, worship, and reliance. It is an acknowledgment of God's sovereignty and a plea for His guidance and intervention. This invocation is a testament to the covenant relationship between God and Israel, where God is not only their Creator but also their protector and provider. It is a call to trust in God's faithfulness and to seek His will in all things.

but not in truth or righteousness
The phrase "but not in truth or righteousness" serves as a rebuke. Despite their outward religious actions, the people's hearts are not aligned with God's standards. "Truth" (אֱמֶת, emet) and "righteousness" (צֶדֶק, tsedeq) are foundational to God's character and His expectations for His people. This critique highlights the disconnect between their professed faith and their actual conduct. It is a call to genuine repentance and transformation, urging them to align their lives with God's truth and righteousness.
