Tzur — The Rock
צוּר
The Rock — Scripture's bedrock metaphor: perfect in work, just in all His ways.
Tzur Yisrael opens Israel's daily redemption blessing; 'Rock of Ages' crossed into every Christian hymnal from Isaiah 26:4. Paul reads the wilderness rock that gave water as Messiah accompanying His people — one Rock, both traditions leaning.
First occurrence
Deut 32:4 — 'The Rock — His work is perfect' (Haazinu's keynote)
