2:18

put to the test: The Greek expression used here is broad in meaning and can be rendered “put to the test” or “tempted,” depending on the context. It is used of temptations as well as major tests of faith. (1Co 10:13; Heb 4:15; 11:17; Re 2:10) Jesus was put to the test in many ways. At the beginning of his ministry, he faced three temptations from Satan, “the ruler of the world.” (Joh 14:30; Mt 4:1-11) During Jesus’ ministry, he was constantly tested​—in some cases, even by his friends. (Mt 16:22, 23) Christ’s ministry ended with the most severe of tests, death by torture. (Heb 12:2) In the face of every test, Jesus kept perfect integrity because of his love for his Father.​—Joh 14:31.

he is able to come to the aid: Because Jesus was tested so thoroughly and suffered so extensively, he fully understands the sufferings of his followers. He is able to “sympathize with our weaknesses.” (Heb 4:15, 16) Paul has shown that Christ comes to the aid of his followers as a merciful and sympathetic high priest. (Heb 2:17; see study note on Heb 2:16.) He fulfills his promise to be with them to the end. (Mt 28:20) He supports them in a variety of ways by means of Jehovah’s holy spirit.​—Lu 11:13; 12:11, 12; Joh 14:13, 14, 16, 26; 15:26.
