What did the post say? "No the text does not say when. It says he that has entered, which is past tense This person who has entered also, in addition to entering into this rest to which they have entered also cease from their own works as God did His."
If it is said in past tense then obviously some have entered as verse 3 states. This rest is the rest to which we receive in Christ Jesus which is the Gospel as verse 2 shows us. He that has entered in to this rest also, in addition to cease from their own works as God did from His. And that ceasing from work was a ceasing from labor on the Seventh Day. His creative work that He did so we can exist. And in this ceasing Exodus says, He was refreshed. So we who have entered into the Rest which is in Christ also, in ADDITION to cease from our labor, our creative work that we do to exist on the Seventh Day which is the Sabbath to be refreshed. As verse 4 and 5 states, For He spake in a certain place (Mt Sinia Ex 20, God did not speak in Gen 2:1-3) of the Seventh Day on this wise, And God did rest from all His works. And in this AGAIN (HE SPEAKS) if they shall enter into my rest. This rest which is the Gospel as verse 3 states. For he that enters into this rest cease from their own works as God did from His.
Exod 31:17 It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.
