Israeli Pottery Vase Mystery

I found this rather large vase at an estate sale but have no idea where it was made. It is a beautiful marble azure-green color with a high polish glaze. It has a very unique wavy square shape. The marks on the bottom make a reference to Psalm 27, verse 1, along with a cursive "y".

It may be a set of Jewish ceremonial vases, or one that is used in a synagogue. I feel certain that it was made in Israel but I can't find anything more about it.

Thanks,

Larry
