Like "say," the word "speak" refers to thoughts and feelings moving from our more internal spiritual levels to our more external ones -- and ultimately from the Lord, who is in a sense the most internal spiritual level of all. This is generally called "influx" and "perception" in the Writings, meaning they are thoughts and feelings that flow in in a complete way from the Lord, rather than being things we have to think about and figure out. On a number of occasions "speak" and "say" are used together; in these cases "speak" refers more to intellectual instruction in matters of thought and "say" refers more to feelings and affections that flow in directly.

1531. 为向我证实以下事实, 即主向属天天使显为太阳, 向属灵天使显为月亮, 蒙主怜悯, 我的内在视觉被打开, 以便我能清楚看到环绕着众多小月亮的闪光月亮, 照以赛亚书上的话说, 它们的光几近于那太阳的光:

月光必像日光. (以赛亚书 30:26)

不过, 我可以看到那太阳, 而月亮则出现我前面右侧.
