pealim.com lets you check the conjugation of more than 2,000 Hebrew verbs online. It is intended for students of Modern Hebrew. That means the Search function may not help you much when translating from the Bible. The Dictionary will also not be very helpful, but the Constructor is the page you will want to use, especially when you want to see the different forms of a root in different stems and conjugations. Modern Hebrew and biblical Hebrew differ from one another in many ways, but the verb forms (not their use!!!) is the same nowadays (with a few exceptions). Enjoy! This is an excellent site!
