John Gill Commentary Mark 8:1

"In those days, when there was again a great multitude, and they had nothing to eat, he called unto him his disciples, and saith unto them," — Mark 8:1 (ASV)

In those days
The Ethiopic version reads, on that day; as if it was on the same day that the deaf man was healed; and so it might be; and on the third day from Christ's coming into those parts; and so is very properly expressed, "in those days"; see (Mark 7:31) , compared with the following verse:

the multitude being very great :
for the number of men that ate, when the following miracle was wrought, were about four thousand; see (Mark 8:9) . The Vulgate Latin, Arabic, and Ethiopic versions add, "again"; referring to the former miracle of the five thousand, who were fed with five loaves, and two fishes, (Mark 6:44) .

And having nothing to eat ;
what they might have brought with them being expended, and they in a desert, where nothing was to be had, nor bought for money:

Jesus called his disciples to him, and saith unto them ;
(See Gill on Matthew 15:32).
