John Gill Commentary John 11:7

"Then after this he saith to the disciples, Let us go into Judaea again." — John 11:7 (ASV)

Then after that
The next day, the third day after he had heard of Lazarus's sickness:

says he to [his] disciples, let us go into Judea again ;
for the country beyond Jordan was distinguished from Judea; (See Gill on Matthew 4:25).
