The texts used for the strokes in the paintings of the Four Seasons of Trees set from the Trees of Life series vary. Fall and Spring use all of Deuteronomy 6, while Summer and Winter use only Deuteronomy 6:4. The Spring and Fall prints are also framed with Deuteronomy 6:4 in gold ink, whereas Winter and Summer do not have painted frames on the originals. There is theology that is fully held by both Judaism and all of Christianity, which supports the choice of these texts.
Many ancient religions, including Judaism and Christianity have holidays that are held around the time of the solstices and equinox.
