Multiple symbolic events occur in the conclusion of this covenant making with Abram that it is fitting to focus on each of them briefly. Adam too was put into a deep sleep in the creation of his wife (Gen 2:21).

This psalm is different from the rest in that it does not have a portion about the unrighteous. Instead this psalm begins in a strongly covenantal way. The word “preserve” is used early in the OT with reference to covenant obligations (Gen 2:15; 17:9-10; 18:19). Here the request is from man to God to keep us within His covenant. Similar statements can be found even within the New Testament (John 10:29; Jude 1:24).
The promises have been made. A sign is given. Now the covenant is made.
These two are not distinct descriptions! They are the same for “out of the abundance of the heart the mouth speaks” (Matt 12:34; Luke 6:45). Vocal ascent requires plenary obedience by fearing the Lord (v. 4). The man who does these things shall not be moved (v. 5). Again Christ taught this in the parable of the two houses (Matt 7:24-27).
