Ziv is the pre-exilic name for the second month of the Hebrew year, roughly corresponding to late April and early May. It appears only in 1 Kings 6:1 and 6:37, both times marking the beginning of Solomon's temple construction. The Aramaic cognate suggests meanings like 'brightness' or 'freshness,' and the Targum expands it as 'the month of the brightness of flowers,' evoking the spring bloom. Later Jewish tradition replaced this with the Babylonian name 'Iyyar.' The Septuagint manuscripts vary widely in how they render it, reflecting uncertainty about these ancient month names.
