Albert Barnes Commentary John 11:6

"When therefore he heard that he was sick, he abode at that time two days in the place where he was." — John 11:6 (ASV)

He remained two days. Probably Lazarus died soon after the messengers left him. Jesus knew this (John 11:11) and did not hurry to Judea, but remained two days longer where he was, so that there might be no possibility of doubt that Lazarus was dead, and so that when he arrived there, Lazarus had been dead four days (John 11:39). This shows, moreover, that he intended to raise him up. If he had not, it could hardly be reconciled with friendship to remain away like this, without any reason, from an afflicted family.

Where he was. At Bethabara (John 1:28; John 10:40), about 30 miles from Bethany. This was about a day's journey, and it makes it probable that Lazarus died soon after the message was sent. One day would have been taken for the message to reach him; two days he remained; one day would have been taken for him to travel to Bethany; so that Lazarus had been dead four days (John 11:39) when he arrived.
