deeds, practices: the things someone does, taken together as a course of conduct that reveals who they are and that they are answered for
This word almost always shows up in the plural, and it names not a single act but the whole pattern of what someone does. English gets close with deeds, doings, or practices, but the point is the sum of a life's conduct rather than one isolated action.
Most often the deeds in view are a person's or a nation's, and they are the very thing God weighs. The prophets pair the word again and again with a call to amend your ways and your doings, and with the promise that people will eat the fruit of their doings, for good or, far more commonly, for ill. So the word carries a built-in note of accountability: your practices are what you will answer for.
A handful of times the deeds belong to God rather than to people. There the same word names his acts in history, the works his people are told to remember and hand down. The thread tying both uses together is simple: deeds reveal the doer, whether the doer is a wayward nation or the God who saves it.
