* To "commit" to someone a certain task means to assign that task to that person. For example, in 2 Corinthians Paul says that God has "committed" (or "given") to us the ministry of helping people be reconciled to God.
* The expression "committed to him the task" could also be translated as "gave him the task" or "entrusted to him the task" or "assigned the task to him."
* The term "commitment" could be translated by, "task that was given" or "promise that was made."
