Adam Clarke on 1 Samuel 25:29

Shall be bound in the bundle of life - Thy life shall be precious in the sight of the Lord: it shall be found in the bundle of life; it shall be supported by Him who is the Spring and Fountain of life, and ever be found united to those who are most favored by the Almighty.

Them shall he sling out - Far from being bound and kept together in union with the Fountain of life, he will cast them off from himself as a stone is cast out from a sling. This betokens both force and violence.
