This is because God knew that there would be an attempt to mislead people into forgetting to keep holy the seventh day as God's Sabbath. But more than this.
Hii ni kwa sababu Mungu alijua kwamba kungekuwepo na jaribio la kuwapotosha watu kuelekea kusahau kuitunza kitakatifu siku ya saba kama Sabato ya Mungu. Bali zaidi ya hili.
