'Master's' in the Bible

“An ox knows its owner,And a donkey its master’s manger,But Israel does not know,My people do not understand.”

And roll you tightly like a ball,To be cast into a vast country;There you will dieAnd there your splendid chariots will be,You shame of your master’s house.’

How then can you repulse one official of the least of my master’s servants and rely on Egypt for chariots and for horsemen?
