So David,Moses and Noah didn't go and they were before that scripture was written.
That does not necessarily mean they weren't "going" after the words were written.
The "resurrection" had not occured yet.
Hebrews 11 talks about these men of old and then verse 16 says about them: "Instead, they were longing for a better country—a heavenly one"
The WT claims the resurrection is one to our old physical bodies. The Bible does not teach this. The second half of 1 Cor 15 describes the resurrection as to a new spiritual body.
