Adam Clarke Bible Commentary

The land of Tema "The southern country" - Θαιμαν, Sept.; Austri, Vulg. They read תימן teiman, which seems to be right; for probably the inhabitants of Tema might be involved in the same calamity with their brethren and neighbors of Kedar, and not in a condition to give them assistance, and to relieve them, in their flight before the enemy, with bread and water. To bring forth bread and water is an instance of common humanity in such cases of distress; especially in those desert countries in which the common necessaries of life, more particularly water, are not easily to be met with or procured. Moses forbids the Ammonite and Moabite to be admitted into the congregation of the Lord to the tenth generation. One reason which he gives for this reprobation is their omission of the common offices of humanity towards the Israelites; "because they met them not with bread and water in the way, when they came forth out of Egypt," Deu 23:4.
