transpose from A1 to A2

Good Morning
I need help because I am trying to transpose the following values, just like the attached file.
I've tried with matrix formula, but I can not get what I want.

in J4
=INDEX($B$4:$F$9,(ROW()-4)*2+1,COLUMN()-9)
copy across and down to N6

in P4
=INDEX($B$4:$F$9,(ROW()-4)*2+2,COLUMN()-15)
copy across and down to T11

j4
