John Gill Commentary Deuteronomy 9:13

"Furthermore Jehovah spake unto me, saying, I have seen this people, and, behold, it is a stiffnecked people:" — Deuteronomy 9:13 (ASV)

Furthermore the Lord spoke to me, saying
After he had given him the two tables, and before his departure from the mount:

I have seen this people ;
took notice of them, their ways, and their works:

and, behold, it is a stiffnecked people ;
unwilling to submit to, and bear the yoke of my commandments; see (Exodus 32:9) .
