Having a couple lines that are similar or copied in several places shouldn't be considered such a bad thing. Repetition reveals similarity, and having clear signals of similarity is really important. It's often more expressive / easier to understand than a single method name. Premature abstractions are way worse than repetition. A poor or insufficient abstraction leads to obfuscation which leads to misunderstanding which leads to novel constructs for the same responsibility. Because a poor abstraction can be really really difficult to back track, you end up with hacky work-arounds to get something done. I think encountering novelty in a codebase is the biggest thing that damages comprehension; and repetition actually enhances comprehensibility.
