Putting on clothes of mourning and not anointing oneself with oil were symbolic actions that in ancient Israel showed grief and sorrow over someone who had died. If it would be helpful to your readers, you could explain the significance of these actions in the text of your translation or in a footnote. Alternate translation: [and act as if you are grieving by wearing dark clothes and not applying any oil to yourself]

Joab is not referring to a specific woman. He means any woman who had been mourning many days. If it would be helpful to your readers, you could use an expression that would be more natural in your language. Alternate translation: [like a woman]
