'Obligated' in the Bible

"Woe to you, you blind guides, who say, 'Whoever swears by the temple, it is nothing; but whoever swears by the gold of the temple, he is obligated.'

'Whoever swears by the altar, it is nothing; but whoever swears by the gift that is on it, he is obligated?'

Therefore he was obligated in all things to be made like his brothers, that he might become a merciful and faithful high priest in things pertaining to God, to make atonement for the sins of the people.
