The earliest prayer links in Va-etchanan come in the first verse, long before what is probably the portion’s most famous passage: the first paragraph of the Shema (Deut. 6:4-9). In fact, there are prayer links galore in the portion’s first word: “va-etchanan” [I pleaded, implored]. Some commentaries examine details of the communication between Moses and God as the portion opens. Some focus, more generally, on what prayer can (or should) mean to regular folks.
**Speaking of communication, please see the query below about sources and editing. Thoughts most welcome.**
