A.T. Robertson Commentary Hebrews 4:10

"For he that is entered into his rest hath himself also rested from his works, as God did from his." — Hebrews 4:10 (ASV)

As God did from his (ωσπερ απο των ιδιων ο θεος). It is not cessation of work, but rather of the weariness and pain in toil. The writer pictures salvation as God's rest which man is to share and God will have perfect satisfaction when man is in harmony with him (Dods).
