This verse, "Wherefore send some with speed, that we also may learn what is your mind," from 2 Maccabees 11:37, essentially means:

"Therefore, quickly send representatives to us so we can understand your intentions and what you are thinking."

Let's break it down:

Wherefore: "Therefore" or "Consequently." It indicates a conclusion or a request based on something previously stated or happening.
Send some with speed: "Send some people quickly" or "Send messengers urgently." The urgency is emphasized.
That we also may learn: "So that we can understand."
What is your mind: "What are your intentions," "what are your plans," "what is your opinion," or "what are you thinking."

Context is Key:

To fully understand this verse, you need to know the context of 2 Maccabees 11. Briefly, the chapter deals with:

Lysias's Desire for Peace: Lysias, a high-ranking Seleucid official, is trying to negotiate a peaceful agreement with the Jewish people, led by Judas Maccabeus. This is after a period of conflict and oppression.
Ongoing Negotiations: Letters are being exchanged to establish terms of peace and understanding.

Therefore, in the context of 2 Maccabees 11:37, the verse is part of a letter urging the Jewish leaders to send representatives to the Seleucid authorities so that clear communication can be established. The Seleucids want to understand the Jewish perspective to solidify the peace agreement.

In summary, it's a plea for clarification and direct communication to facilitate a peace agreement.
