Reformed Theological Seminary has recently created a seven week intensive class for learning the biblical languages (including Aramaic). It is a great opportunity for pastors and ministry leaders (and anyone else) to learn the languages without having to leave their current ministry context full time
For added encouragement, Martin Luther has a good word about the importance of learning the biblical languages:
We will not long preserve the gospel without the languages. The languages are the sheath in which this sword of the Spirit is contained; they are the casket in which this jewel is enshrined; they are the vessel in which this wine is held; they are the larder in which this food is stored; and, as the gospel itself points out, they are the baskets in which are kept these loaves and fishes and fragments.
