Context for Zenos: In this verse, Zenos describes praying “in the midst of thy congregations,” the first setting in which he was not alone. In verse 8, he had given priority to personal prayer, not to prayer designed for its public effect. Now he affirms that individual prayer can occur even in public, with the clear implication that Yahweh hears him while ignoring those who are praying to be seen of others.
Context for Alma’s discourse: Continuing to assume that these farmers’ exclusion from the Zoramite open-air synagogue was social and not legal, then Alma may be suggesting the radical notion that they can pray even in the same place that the Zoramite prayer is being repeatedly pronounced aloud, because Yahweh can hear their quiet prayers.
