sabbatical observance at that time, but that, whilst the way was practically opened, it was through the decalogue that it was raised into a legal institution (see Exo 10:8.). שׁבּתון is an abstract noun denoting “rest,” and שׁבּי a concrete, literally the observer, from which it came to be used as a technical term for the seventh day of the week, which was to be observed as a day of rest to the Lord.
verses 27-30
On the seventh day some of the people went out to gather manna, notwithstanding Moses' command, but they found nothing. Whereupon God reproved their resistance to His commands, and ordered them to remain quietly at home on the seventh day. Through the commandments which the Israelites were to keep in relation to the manna, this gift assumed the character of a temptation, or test of their obedience and faith (cf. Exo 16:4).

It is ordinarily met with in the peninsula of Sinai in the months of June and July, and sometimes even in May. It is most abundant in the neighbourhood of Sinai, in Wady Feirân and es Sheikh, also in Wady Gharandel and Taiyibeh, and some of the valleys to the south-east of Sinai (Ritter, 14, p. 676; Seetzen's Reise iii. pp. 76, 129). In warm nights it exudes from the branches of the tarfah-tree, a kind of tamarisk, and falls down in the form of small globules upon the withered leaves and branches that lie under the trees; it is then gathered before sunrise, but melts in the heat of the sun.
