25.24 The IMPERFECT TENSE indicates an action in the past that was ongoing, or used to take place over a period of time. Think of it as a bit of video of an action from the past. Therefore, the imperfect is usually translated as was/were verbing, used to verb, or kept verbing.
For example:
- ἐδίδουν = I was giving, I used to give, I kept giving
- ἐδίδοσαν = they were giving, they used to give, they kept giving
