Through very subtle literary techniques, the Torah has the ability to transmit a meaningful message, without stating it explicitly.
A strong example of this technique relates to the question of whether Shmini Atzeret (the "Eighth Day of Assembly") is an independent holiday, or a continuation of Sukkot.
The use of this technique appears in Bemidbar (Numbers) 29:
In verse 12 the Torah describes the Sukkot festival as a 7 day holiday.
