Plenty of Bible programs and apps are available for purchase at prices that range from a dollar to more than $1,000. But many excellent free sites provide a wealth of materials and capabilities. Several carry public domain commentaries, but each of the sites below includes helpful resources. Some include tools that are more technical, others are accessible to any user. These were suggested by fellow Covenanters so check out what others are using.
Don’t let the title fool you. “Studylight” has many of the commentaries and Bibles that are unavailable on other sites. It has one of the better interlinear displays. It also includes various devotionals and Bible reading plans.
“The Text This Week” serves as a resource center connecting the preacher to a wealth of articles, online commentaries, artwork, children’s sermons, prayers for worship, and more for each text in the lectionary.
For a site that might initially seem sparse, “Bible Hub” has a lot to offer, including Google maps that give access to what some of the biblical sites look like today. Their interlinear Bible and parallel texts also are very good.
