Numbers 28:3-8, 10

Say to them, ‘These are the offerings you must bring to the LORD: two male lambs, a year old, as a burnt offering each day. They must have nothing wrong with them. Offer one lamb in the morning and the other lamb at twilight. Also bring a grain offering of two quarts of fine flour, mixed with one quart of oil from pressed olives. This is the daily burnt offering which began at Mount Sinai; its smell is pleasing to the LORD. Offer one quart of wine with each lamb as a drink offering; pour it out to the LORD at the Holy Place. Offer the second lamb at twilight. As in the morning, also give a grain offering and a drink offering. This offering is made by fire, and its smell is pleasing to the LORD.

This is the burnt offering for every Sabbath, in addition to the daily burnt offering and drink offering.
