Morris Louis's Veil paintings constituted his first fully resolved series of mature paintings. Begun in 1958 and painted during a period of about fourteen months, the Veils presented Louis with the ideal vehicle for his stain technique and yielded a wide variety of romantic and atmospheric paintings within a similar compositional structure. He seems to have begun with dark, brooding Bronze veils, but worked his way towards more intensely colored paintings as the series progressed.

Beth Tzadik is an especially richly colored Veil, with intense blues and greens glowing through the overlaying of poured paint. The Veil composition is also fully resolved in this painting, with the entire field of canvas nearly filled by the image, emphasizing its expansive nature. The interior of Beth Tzadik is rich in linear effects, which result from the edges of each successive layer of paint as it was poured from the top of the canvas and directed along a controlled path toward the bottom edge.

Louis was not especially interested in titles for his paintings, most of which remained untitled at his death in 1962. He had used transliterations of Greek letters as the titles of two Unfurled paintings exhibited during his lifetime. As a result, it was the decision of the artist's Estate to continue to use Greek letters in titling the remainder of that series, while transliterations of Hebrew letters were used to title those Veil paintings, including Beth Tzadik, that had remained untitled by him.
