The rest of this section contains the record of the Israelites' reaction to the giving of the Law and God's reason for giving it as He did. He wanted the people to reverence Him and therefore not to sin (v. 20).343
"It can be argued that in the present shape of the Pentateuch, the Decalogue (Ex 20:1-17) is intended to be read as the content of what Moses spoke to the people upon his return from the mountain in 19:25. After the Decalogue, the narrative in 20:18-21 looks back once again to the people's fear in 19:16-24. In retelling this incident, the second narrative fills the important gaps' in our understanding of the first."344
"The Book of the Covenant begins technically with Exodus 20:22, having been separated from the Decalogue by a brief narrative (vv. 18-21) describing the people's response to the phenomena accompanying Moses' encounter with Yahweh on Sinai (cf. 19:16-25). The technical term ordinances' (mispatim), which describes the specific stipulations of the covenant, does not occur until 21:1, so 20:22-26 serves as an introduction to the stipulation section. This introduction underlines Yahweh's exclusivity, His self-revelation to His people, and His demand to be worshiped wherever He localizes His name and in association with appropriate altars."345
God evidently spoke the Ten Commandments in the hearing of all the Israelites (19:9; 20:19, 22) to cause them to fear Him (v. 20). The people were so awestruck by this revelation that they asked Moses to relay God's words to them from then on (v. 20), which he did (v. 21).
"This verse [v. 20] contrasts two types of fear': tormenting fear (which comes from conscious guilt or unwarranted alarm and leads to bondage) or salutary fear (which promotes and demonstrates the presence of an attitude of complete trust and belief in God; cf. the fear of the LORD God' beginning in Gen 22:12). This second type of fear will keep us from sinning and is at the heart of the OT's wisdom books (cf. Prov 1:7; Eccl 12:13 et al.)."346
"Whereas 19:16-24 looks at the people's fear from a divine perspective, 20:18-21 approaches it from the viewpoint of the people themselves. What we learn from both narratives, therefore, is that there was a growing need for a mediator and a priesthood in the Sinai covenant. Because of the people's fear of God's presence, they are now standing afar off' (20:21). Already, then, we can see the basis being laid within the narrative for the need of the tabernacle (Ex 25-31). The people who are afar off' must be brought near to God. This is the purpose of the instructions for the tabernacle which follow this narrative."347
