@MMS, found it on page 8 of Rav Ħayyim Palaji’s ‘Artzοt Haħayyim’ printed by Shmelke Yosef Shmer & Co. at Y'rushalayim, Erretz Yisra'el in 5632 (1871/72).There is a fascinating remez ('hint') regarding Iron, Matriarchs, Patriarchs and Erretz Yisra'el in the last book of Tοrah, brought down by the 19th-century Turkish Rav, Ħayyim Palaji (somewhere in his work entitled ‘Artzοt Haħayyim’, in the name of his son Rav Yitzħaḳ Palaji). God willing, I will find it before Yom Kippur.
The initial letters of אֲֲֲבָָָנֶֶֽיהָָָ בַַרְְזֶֶֶל וּמֵֵֽהֲֲֲרָָָרֶֶֽיהָָָ תַַּחְְצֹֹב avaneha varzel umeharareha taħtzοv ('[a land whose] rocks are iron and from [whose] mountains you shall hew [copper]', see D'varim 8:9) spell out the word אָָָבוֹֹת avοt ('patriarchs'), whereas בַַּרְְזֶֶֶל barzel ('iron') represents the matriarchs; and the word אֲֲֲבָָָנֶֶֽיהָָָ avaneha ('its rocks') is an anagram of בַַּנָָָּאֶֶֽיהָָָ banna'eha ('its builders'). From here we learn that Erretz Yisra'el is built upon the virtues of the Patriarchs and the Matriarchs!
