יחזקאל, פרק כ׳, פסוק כ׳

Observing and sanctifying the Sabbath serves as a direct testimony to the special connection between God and the Israelites. The act of keeping these days holy is driven by a distinct purpose rather than being a mere routine. They must be deliberately set apart and dedicated to act as a clear, defining mark. Through this intentional practice, the Sabbath functions as a lasting sign meant to lead to the true knowledge and recognition of God [מצודת דוד].
