The people took their dough before it was leavened, etc. - There was no time now to make any regular preparation for their departure, such was the universal hurry and confusion. The Israelites could carry but little of their household utensils with them; but some, such as they kneaded their bread and kept their meal in, they were obliged to carry with them. The kneading troughs of the Arabs are comparatively small wooden bowls, which, after kneading their bread in, serve them as dishes out of which they eat their victuals. And as to these being bound up in their clothes, no more may be intended than their wrapping them up in their long, loose garments, or in what is still used among the Arabs, and called hykes, which is a long kind of blanket, something resembling a highland plaid, in which they often carry their provision, wrap themselves by day, and sleep at night. Dr. Shaw has been particular in his description of this almost entire wardrobe of an Arab. He says they are of different sizes and of different qualities, but generally about six yards in length, and five or six feet broad. He supposes that what we call Ruth's veil, Ruth 3:15, was a hyke, and that the same is to be understood of the clothes of the Israelites mentioned in this verse. See his Travels, p. 224, 4th edition.

Probably like the kneading-trough of the Arabs; comparatively small wooden bowls, which also serve them for dishes. Their being bound up in their clothes may mean no more than their being wrapped up in their hykes, or long, loose, garments.

The Blood
Now, at the time of which this Book of Exodus speaks, Egypt was exposed to a terrible peril. Jehovah himself was about to march through the streets of all the cities of Egypt. It was not merely a destroying angel, but Jehovah himself; for thus it is written, "I will pass through the land of Egypt this night, and will smite all the first-born in the land of Egypt, both man and beast." No one less than I AM, the great God, had vowed to "cut Rahab" with the sword of vengeance. Tremble, ye inhabitants …

Appendix xii. The Baptism of Proselytes
ONLY those who have made study of it can have any idea how large, and sometimes bewildering, is the literature on the subject of Jewish Proselytes and their Baptism. Our present remarks will be confined to the Baptism of Proselytes. 1. Generally, as regards proselytes (Gerim) we have to distinguish between the Ger ha-Shaar (proselyte of the gate) and Ger Toshabh (sojourner,' settled among Israel), and again the Ger hatstsedeq (proselyte of righteousness) and Ger habberith (proselyte of the covenant). …

Hope for the Heathen
Throughout his ministry Isaiah bore a plain testimony concerning God's purpose for the heathen. Other prophets had made mention of the divine plan, but their language was not always understood. To Isaiah it was given to make very plain to Judah the truth that among the Israel of God were to be numbered many who were not descendants of Abraham after the flesh. This teaching was not in harmony with the theology of his age, yet he fearlessly proclaimed the messages given him of God and brought hope …
