Welcome back to the Wefugees Community and thank you for your question.
We discussed a very similar one already here before. Please follow the link for more information. On this website (here referring specifically to Berlin though) you may find a detailed list of the requirements. To answer in short: Yes, in general the livelihood of you and your family (foreign family members) needs to be secured and you should not receive money from the Jobcenter or the Social Welfare Office (Sozialamt). There are allowances, as the "Kindergeld" for instance, which on the other hand do not have a negative effect on your application.
I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
