The Star of David has six triangles surrounding one hexagon. Drawing same sized circles around a main circle always ends up in six - not five, not seven. This alludes to the six days of creation in Genesis and the one day of rest; to the six working days and the one day of rest… Six years of slavery and freedom on the seventh… Six years of planting and letting the land rest on the seventh… six candlesticks surrounded the Menorah in the Tabernacle, three from each side.
In this photomontage I put the White Lilium Candidum on six Israeli coins that show the Lilium engraved on stone and it fits nicely the six and one coins that allude to the Star of David.
