'Teachers' in the Bible

For if the inheritance [of what was promised] is based on [observing] the Law [as these false teachers claim], it is no longer based on a promise; however, God granted it to Abraham [as a gift] by virtue of His promise.

These men [the Judaizers] eagerly seek you [to entrap you with honeyed words and attention, to win you over to their philosophy], not honorably [for their purpose is not honorable or worthy of consideration]. They want to isolate you [from us who oppose them] so that you will seek them.

A little leaven [a slight inclination to error, or a few false teachers] leavens the whole batch [it perverts the concept of faith and misleads the church].
