Halakhah for Megillah 1:10
אֵין בֵּין בָּמָה גְדוֹלָה לְבָמָה קְטַנָּה אֶלָּא פְסָחִים. זֶה הַכְּלָל, כָּל שֶׁהוּא נִדָּר וְנִדָּב, קָרֵב בַּבָּמָה. וְכֹל שֶׁאֵינוֹ לֹא נִדָּר וְלֹא נִדָּב, אֵינוֹ קָרֵב בַּבָּמָה:
There is no difference between a large bamah (sacrificial mound) and a small bamah but pesachim (Pesach offerings). [This, when the bamoth were permitted. A large bamah is a congregational sacrificial mound, as that of Nov and Giveon. A small bamah is one that each individual makes for himself. Pesachim and all (offerings) like pesachim, i.e., obligatory offerings having a set time, such as temidim and mussafim, (are offered on a large bamah, but not on a small one); but obligatory offerings having no set time, such as the bullock of forgetfulness of the congregation and the goats for (unwitting) idolatry were not offered even on a large bamah.] This is the rule: Whatever is vowed and donated may be offered on a (small) bamah; whatever is not vowed and donated may not be offered on a bamah.
