Dalet: religious or masonic?

Dalet, ד , is the fourth letter in several Semitic languages. In Hebrew 'dalet' means door. Some say that the shape is reminiscent of a tent flap opening for a door. In Greek the letter is called 'delta', Δ. So, the dalet inside the delta reinforces itself. D also represents David, the king. A double dalet in the shape of a six point star, also stands for DaviD, and by extension Judaism. For Christians the triangle represents the Trinity. The six pointed star, is the Star of Creation (the world was created in six days).

Masonic lore employs symbol and allegory, often open ended to interpretation. Much of masonic ritual relates to death and resurrection. They often borrow symbols from religion or the occult, often employed in a different matter, than the source. Now, weave your interpretation.
A smaller stone by the bigger one, has a triangle with a symbol for a 32° mason. It seems Maloney may not have been Jewish after all.
