Am I obligated to "honour [my] mother" (if she became a needy widow and) if she had given me up?
If someone was given up by his or her own mother (as in the quote below), is one obligated to "honour your mother" (by which I mean, any and all interpretation of the command to "honour your mother", which includes financial and/or housing support, especially if the mother is a needy widow, later in her life?)
אִם לֹא רָצְתָה הָאֵם שֶׁיִּהְיוּ בָּנֶיהָ עִמָּהּ אַחַר שֶׁגְּמָלָתָן, אֶחָד זְכָרִים וְאֶחָד נְקֵבוֹת, הָרְשׁוּת בְּיָדָהּ, וְנוֹתֶנֶת אוֹתָם לַאֲבִיהֶם, אוֹ מַשְׁלֶכֶת אוֹתָם לַקָּהָל אִם אֵין לָהֶם אָב, וְהֵם מְטַפְּלִים בָּהֶם, אֶחָד זְכָרִים וְאֶחָד נְקֵבוֹת:
Translation: "If the mother did not want her children to be with her after they were weaned, whether male or female, that is her prerogative, and she may give them to their father, or send them to the [care of] the community if they do not have a father, and the community raises them, whether male or female."
"Possible Duplicate" says somebody, In regards to Torah and Rabbinical writings, how does "honor your father and mother" work when you've been raised in an abusive household?
However, the difference between these two postings: one is talking about being raised in an abusive household while knowing one's parents, whereas my posting here is about being given up for adoption, while still a toddler (after being weaned אַחַר שֶׁגְּמָלָתָן), and only knowing of your parent's identity "later in her life".
