Psalms 70:1
1Hurry, God, to deliver me. Come quickly to help me, LORD.
Wesley: Make haste—this and the following verses nearly the same with Psalm 40:13–17. Deliver from enemies; he doubles the request to express vehemency. The twin petitions (deliver / help) refuse leisurely religion when danger is near.
Haste is begged because need is authentic and prayer is the appointed means. Grace that can deliver still summons urgent asking; delay on our side would be presumption.
Calvin: under sense of danger he earnestly entreats God to make haste. Although God does not always answer at the very moment we call, it is our duty to pray that he would make haste. The repetition shows intensity of desire.
Urgency in prayer does not deny providence’s timing; it confesses helplessness. Make haste is the poor saint’s cry, not unbelief.
