'Unaware' in the Bible

Or if a person touches anything unclean, {whether} an unclean [wild] animal's dead body or an unclean domestic animal's dead body or an unclean swarmer's dead body, but {he is unaware of it}, he [is] unclean and he is guilty.

Or when he touches human uncleanness, {namely} any uncleanness of his by which he might become unclean, but {he is unaware of it}, and he himself finds out, then he will be guilty.

Or when a person swears, speaking thoughtlessly with [his] lips, to do evil or to do good {with regard to} anything that {the person} in a sworn oath speaks thoughtlessly, but {he is unaware of it}, he will be guilty {in any of} these.
