Reply To: Classics and Beyond Vayakhel – A Greater Catch:

I heard once it says in the aseres hadibros זכור את יום השבת לקדשו remember shabbos by sanctifying it ‘ששת ימים תעבוד ועשית ‘כל מלאכתך then you won’t forget when is shabbos and will be able to do all your work in six days, even more than necessary for your sustenance, וביום השביעי שבת לה’ אלקיך the seventh day will be a rest day for Hashem your G-d ‘לא תעשה ‘כל מלאכה you will be able to rest completely and even not doing what is necessary for your sustenance.
What is interesting why it does not say by the six days over here כל מלאכה, all your work as explained? Could be that it does not say to remember shabbos, so he does not forget it and there is no need to tell that one can do all the work in the six days.
