Seal of Solomon in the context of "Pentacle"

The Star of David (Hebrew: מָגֵן דָּוִד, romanized: Māḡēn Dāvīḏ, [maˈɡen daˈvid] , lit. 'Shield of David') is a symbol generally recognized as representing both Jewish identity and the Jewish people's ethnic religion, Judaism. Its shape is that of a hexagram: the compound of two equilateral triangles.

A derivation of the Seal of Solomon was used for decorative and mystical purposes by Kabbalistic Jews and Muslims. The hexagram appears occasionally in Jewish contexts since antiquity as a decorative motif, such as a stone bearing a hexagram from the arch of the 3rd–4th century Khirbet Shura synagogue. A hexagram found in a religious context can be seen in the Leningrad Codex, a manuscript of the Hebrew Bible from 11th-century Cairo.

The Testament of Solomon is a pseudepigraphical composite text ascribed to King Solomon but not regarded as canonical scripture by Jews or Christian groups. It was written in the Greek language, based on precedents dating back to the early 1st millennium AD, but was likely not completed in any meaningful textual sense until sometime in the Middle Ages. In its most noteworthy recensions, the text describes how Solomon was enabled to build his temple by commanding demons by means of a magical ring that was entrusted to him by the archangel Michael.

The flag of Israel was officially adopted on 28 October 1948. It is a white banner with three blue (tekhelet) symbols: a pair of horizontal tallit-like stripes above and below a centred Star of David. Relevant Israeli legislation describes the flag's dimensions as 160 cm (63 in) by 220 cm (87 in), thereby fixing the proportion to a ratio of 8:11. But variants can be found at a wide range of proportions, with 2:3 also common.

The symbols' colour is generically described as "dark sky-blue" and may differ from flag to flag, ranging from pure blue (sometimes shaded almost as dark as navy blue) to hues about 75% toward pure cyan and shades as light as very light blue. An early version of the flag was displayed at a procession marking the third anniversary of the founding of Rishon LeZion in 1885. A similar version was designed for the Zionist movement in 1891. The highly distinctive Star of David, which recalls the legendary Seal of Solomon, has been prominent as a widely recognized Jewish symbol since the 17th century and was formally endorsed by the First Zionist Congress in 1897.
