Teach your children to understand the Bible in Hebrew, Greek, and Aramaic.
.
Hebrew is useful in some ways, but requires several years of intense study to master, and it is unnecessary!
The JPS Tanakh was an independent English translation of the old testament done by the very best Hebrew scholars, and it has no significant differences from the KJV.
Studying Greek will simply get you into arguments with those that have used deliberate mistranslation of Greek words as a foundation for their man made theology.
Aramaic is of no value for most because there are very few ancient Aramaic MS in existence to work with.
