The apostle seems to have had this scripture in his view, and referred it to the times in which he lived, when, after pointing out the heavy afflictions the church then endured, he quotes a part of this very passage, Romans 8:36. And it is beautiful and encouraging to remark, how contemptuously the apostle speaks of the vain attempts of persecutors to separate from Christ: and what a blessed conclusion he makes. Romans 8:37 etc.

Psalms 44:17-22
17 All this is come upon us; yet have we not forgotten thee, neither have we dealt falsely in thy covenant.
18 Our heart is not turned back, neither have our stepsa declined from thy way;
19 Though thou hast sore broken us in the place of dragons, and covered us with the shadow of death.
20 If we have forgotten the name of our God, or stretched out our hands to a strange god;
21 Shall not God search this out? for he knoweth the secrets of the heart.
22 Yea, for thy sake are we killed all the day long; we are counted as sheep for the slaughter.
