Final answer:
When Saul starts to get jealous of David, he tries to eliminate him by attempting to kill him multiple times.
Step-by-step explanation:
When Saul starts to get jealous of David, he tries to eliminate David by attempting to kill him multiple times. For example, in 1 Samuel 18:10-11, Saul throws a spear at David while he is playing the harp. In 1 Samuel 19, Saul sends messengers to David's house to kill him, but David escapes with the help of his wife, Michal.
These attempts to harm David stem from Saul's jealousy and fear that David will become more popular and take the throne from him. Saul sees David as a threat to his kingship and tries to eliminate him to secure his own power.
