Mark 07

Mk.7:24And He entered a house and wanted no one to know it, but He could not be hidden.

Why does Jesus not want anyone to know? Didn't he himself said:

Lk8:16 “No one, when he has lit a lamp, covers it with a vessel or puts it under a bed, but sets it on a lampstand, that those who enter may see the light. "

But if we read further:
Mk.7:26“Let the children be filled first, for it is not good to take the children’s bread and throw it to the little dogs.”

Jesus was sent to Israel. The task to spread salvation to the rest of the world was the job of the apostles:
Acts1:8"and you shall be witnesses to Me^[a] in Jerusalem, and in all Judea and Samaria, and to the end of the earth.”
