In the list of sacrifices that appears in our parasha we find a series of repetitious phrases.
“The burnt offering of the Sabbath in its Sabbath” (28:10)
“And a tenth and a tenth of fine flour” (28:13)
“This is the burnt-offering, month by month” (28:14)
“A tenth and a tenth you shall offer” (28:21, 28)
and so forth.
